Technical Field

[0001] The present invention relates to the technical field of flexible direct current power transmission, and in particular to a construction method and device for a flexible direct current converter station. Background Art

[0002] Flexible DC transmission is a new type of transmission technology based on voltage source converter, turn-off switch device and pulse width modulation (PWM) technology. It is a new generation of DC transmission technology and the most advanced power electronics technology currently in engineering application. At present, flexible DC converter stations with rated voltage of more than 200kV onshore DC are all constructed in outdoor flat-laying style. The DC field, valve hall, starting circuit, connection transformer, AC distribution device and other functional areas are arranged in sequence according to the electrical process flow, which occupies a large area and is not conducive to the construction of flexible DC converter stations in urban areas with tight land resources.

[0003] However, the existing flat-type flexible DC converter station construction method has a large footprint, and the construction contents of various disciplines are not coordinated and optimized with the overall plan iteration, which is not suitable for urban flexible DC converter stations with limited land resources. Summary of the invention

[0005] In order to solve the above technical problems, an embodiment of the present invention provides a method for constructing a flexible DC converter station, comprising the following steps:

[0006] Obtain converter station data and compact construction requirements of the target flexible DC converter station;

[0007] generating initial construction parameters according to preset electrical equipment construction data and the converter station data, and optimizing the initial construction parameters by the equipment optimization parameters in the compact construction requirements to obtain first construction parameters;

[0008] The first construction parameters are optimized in sequence through preset hydraulic HVAC construction parameters, structural building construction parameters and general layout construction parameters to obtain general construction parameters;

[0009] The total construction parameters are judged according to the compact construction requirements. When it is determined that the total construction parameters meet the compact construction requirements, the total construction parameters are output as a construction scheme, and the target flexible DC converter station is constructed according to the construction scheme.

[0010] The construction method provided by the present invention first obtains the converter station data and compact construction requirements of the target flexible DC converter station, that is, obtains the basic data of the converter station that needs to be compactly constructed and the basic requirements for compact construction of the converter station. After determination, the initial construction parameters of the converter station are generated according to the electrical equipment construction data and the converter station data, that is, the construction parameters of the electrical equipment functional room of the converter station are generated, and after generation, the initial construction parameters are optimized for the first time through the equipment optimization parameters to obtain the first construction parameters to improve the accuracy of the first construction parameters. The first construction parameters are optimized through the hydraulic HVAC construction parameters, the structural building construction parameters and the general drawing construction parameters to further improve the accuracy of the total construction parameters. Then, according to the compact construction requirements, it is judged whether the total construction parameters meet the requirements to ensure the effectiveness and practicality of the total construction parameters. Only when it is judged that it meets the requirements, it is output as a construction plan and the target flexible DC converter station is constructed according to the output construction plan. The present invention collaboratively optimizes the construction parameters of the converter station through various professions, including electrical equipment, hydraulic HVAC, structural architecture and general layout construction, and makes a compact judgment on the overall construction parameters after optimization, which can effectively improve the accuracy and practicality of the compact construction plan of the converter station.

[0011] As a preferred example, the step of optimizing the initial construction parameters by using the equipment optimization parameters in the compact construction requirements to obtain the first construction parameters includes:

[0012] Obtaining device dimension data, air clearance data, and anti-magnetic shielding data of the initial construction parameters;

[0013] Obtaining corresponding size optimization parameters, air clearance optimization parameters and anti-magnetic optimization parameters from the compact construction requirements according to the equipment size data, the air clearance data and the anti-magnetic shielding data;

[0014] The device size data, the air clearance data and the anti-magnetic shielding data are optimized according to the size optimization parameter, the clearance optimization parameter and the anti-magnetic optimization parameter respectively to obtain the first construction parameter.

[0015] In order to improve the accuracy of the first construction parameters, the construction method provided by the present invention optimizes the initial construction parameters from three aspects: device size data, air clearance data, and anti-magnetic shielding data of the initial construction parameters. By matching the corresponding size optimization parameters, clearance optimization parameters, and anti-magnetic optimization parameters in the compact construction requirements, the device size data, air clearance data, and anti-magnetic shielding data are optimized respectively to ensure that the first construction parameters meet the compact construction requirements, and at the same time, the accuracy and effectiveness of the compact construction of the optimized first construction parameters can be effectively improved.

[0016] As a preferred example, the optimizing the device size data, the air clearance data and the anti-magnetic shielding data to obtain the first construction parameter includes:

[0017] Parsing the equipment size data to obtain converter valve data, connection transformer data and DC field data;

[0018] The converter valve data, the connection variable data and the DC field data are optimized respectively by using the size optimization parameters to obtain a first converter valve parameter, a first connection variable parameter and a first DC field parameter;

[0019] The first converter valve parameter, the first connection variable parameter and the first DC field parameter are integrated into the first construction parameter to update the first construction parameter.

[0020] When optimizing the equipment size data, the optimization method provided by the present invention is to optimize the converter valve data, connection transformer data and DC field data in the equipment size data respectively by obtaining the size optimization parameters required by the compact construction. Since the above three types of equipment occupy a large area, the optimization of the equipment size can be simplified to optimizing the arrangement of the above three types of equipment, so as to reduce the floor space of the equipment, improve the equipment size optimization effect and ensure that the parameters meet the compact construction requirements.

[0021] As a preferred example, the optimizing the device size data, the air clearance data and the anti-magnetic shielding data to obtain the first construction parameter includes:

[0023] Performing a simulation discharge experiment on the limited position data according to the gap shape optimization parameter and the insulation optimization parameter in the clearance optimization parameter to obtain a simulation experiment result;

[0024] A corresponding first gap parameter and a first insulation parameter are determined according to the simulation experiment result, and the first gap parameter and the first insulation parameter are integrated into the first construction parameter to update the first construction parameter.

[0025] When considering optimizing the air clearance data, since the air clearance is generally calculated based on the insulation level of each electrical device, the construction method provided by the present invention is to optimize the gap shape and insulation level of the limited position data in the air clearance data. The limited position data is simulated by the gap shape optimization parameters and insulation optimization parameters included in the compact construction requirements, and then the first gap parameter and the first insulation parameter that can better reduce the air clearance data are selected according to the obtained simulation results and integrated into the first construction parameters to improve the optimization effect of the air clearance data while ensuring that the parameters meet the compact construction requirements.

[0026] As a preferred example, the optimizing the device size data, the air clearance data and the anti-magnetic shielding data to obtain the first construction parameter includes:

[0027] Performing simulation calculation on the anti-magnetic shielding data according to the anti-magnetic optimization parameters to obtain simulation calculation results;

[0028] A corresponding first anti-magnetic parameter is determined according to the simulation calculation result, and the first anti-magnetic parameter is integrated into the first construction parameter to update the first construction parameter.

[0029] In order to improve the anti-magnetic shielding effect of the construction parameters while ensuring that the construction parameters meet the compact construction requirements, the present invention will conduct simulation experiments on the anti-magnetic shielding data according to the anti-magnetic optimization parameters in the compact construction requirements, and select the first anti-magnetic parameter that can better improve the anti-magnetic shielding effect according to the simulation experiment results and integrate it into the first construction parameter to improve the optimization effect of the anti-magnetic shielding data while ensuring that the parameters meet the compact construction requirements.

[0030] As a preferred example, the first construction parameters are constructed in sequence through preset hydraulic HVAC construction parameters, structural building construction parameters and general layout construction parameters to obtain the general construction parameters, including:

[0031] Optimizing and constructing the first construction parameter according to the hydraulic HVAC construction parameter to obtain a second construction parameter;

[0032] Comparing the second construction parameter with the compact construction requirement to obtain a first comparison result;

[0033] When the first comparison result is that the second construction parameter meets the compact construction requirement, the second construction parameter is optimized and constructed by using the structural building construction parameter and the general plan construction parameter to obtain the general construction parameter.

[0034] In order to ensure that the optimized construction parameters meet the compact construction requirements, the construction method provided by the present invention will judge whether the second construction parameter meets the compact construction requirements after obtaining the second construction parameter from the first construction parameter through the hydraulic and HVAC construction parameters, that is, compare it with the compact construction requirements, and determine whether it meets the compact construction requirements based on the first comparison result. Only on the premise that it is determined that it meets the compact construction requirements, will the second construction parameter be adjusted through the structural building construction parameters and the general plan construction parameters to achieve multi-professional collaborative optimization of the converter station construction parameters, including electrical equipment and hydraulic and HVAC.

[0035] As a preferred example, the step of optimizing the second construction parameters by using the structural building construction parameters and the general plan construction parameters to obtain the general construction parameters includes:

[0036] The second construction parameter is optimized by the structural building construction parameter to obtain a third construction parameter;

[0037] Comparing the third construction parameter with the compact construction requirement to obtain a second comparison result;

[0038] When the second comparison result is that the third construction parameter meets the compact construction requirement, the third construction parameter is optimized and constructed by using the overall construction parameter to obtain the overall construction parameter.

[0039] In order to further ensure that the optimized construction parameters meet the compact construction requirements, the construction method provided by the present invention will also judge whether the third construction parameter meets the compact construction requirements after the second construction parameter is constructed and adjusted through the structural building construction parameter, that is, it will be compared with the compact construction requirements. Only when it is determined that it meets the compact construction requirements can the next construction adjustment be made to further ensure that the adjusted third construction parameter also meets the compact construction requirements, and at the same time, it can also achieve coordinated optimization between the structural building profession, the electrical equipment profession, and the hydraulic and HVAC profession.

[0040] As a preferred example, the optimizing and constructing the third construction parameter by using the overall diagram construction parameter to obtain the overall construction parameter includes:

[0041] The third construction parameter is optimized and constructed by using the overall construction parameter to obtain a fourth construction parameter, and the fourth construction parameter is output as the overall construction parameter.

[0042] After optimizing and adjusting the construction parameters of the converter station through the above-mentioned professions, the basic appearance diagram of the converter station construction parameters, that is, the basic construction structure diagram of the converter station, can be determined, and then the third construction parameters optimized and adjusted by the above-mentioned professions can be adjusted through the overall construction parameters to obtain the optimized overall construction parameters of the converter station.

[0043] As a preferred example, the determining of the total construction parameters according to the compact construction requirement further includes:

[0044] When it is determined that the total construction parameters do not meet the compact construction requirements, the compact construction requirements are adjusted according to the total construction parameters, and the process returns to generating the initial construction parameters according to the electrical equipment construction data and the converter station data.

[0045] When judging the compact construction requirements for the total construction parameters, if the judgment result is that the total construction parameters do not meet the compact construction requirements, it is necessary to return to the step of generating the initial construction parameters based on the electrical equipment data and the converter station data. At the same time, the compact construction requirements will be adjusted according to the generated total construction parameters to improve the accuracy of the subsequent optimization adjustment of the initial construction parameters by various disciplines according to the compact construction requirements.

[0054] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0055] Embodiment 1

[0056] Please refer to Figure 1 , is a flow chart of an embodiment of a method for constructing a flexible DC converter station provided by the present invention, including steps 101 to 104, each of which is specifically as follows:

[0057] Step 101: Obtain converter station data and compact construction requirements of a target flexible DC converter station.

[0058] The construction method provided in the embodiment of the present invention first needs to obtain the basic parameters of the target flexible DC converter station, including the converter station data that needs to be optimized for construction parameters and the compact construction requirements. Among them, the converter station data, i.e. the basic data of the converter station, includes the process layout process of each functional plant area of ​​the converter station and the specific electrical equipment required for each functional area; and the compactness requirements include various parameters such as the professional optimization parameters of the converter station, the available site area, and the site utilization rate of each profession.

[0059] Step 102: generating initial construction parameters according to preset electrical equipment construction data and the converter station data, and optimizing the initial construction parameters by the equipment optimization parameters in the compact construction requirements to obtain first construction parameters.

[0060] After obtaining the basic data of the converter station, i.e., the converter station data and the compact construction requirements, the initial construction parameters of the converter station will be generated according to the converter station data and the preset electrical equipment construction data, wherein the electrical equipment construction data refers to the specific connection scheme and basic construction method of each electrical equipment in the converter station data. After completing the layout construction of the basic electrical equipment of the converter station and obtaining the initial construction parameters, the initial construction parameters will be optimized through the equipment optimization parameters in the compact construction requirements to ensure that the optimized first construction parameters meet the compact construction requirements, and at the same time, the arrangement of the electrical equipment in the initial construction parameters can be optimized as much as possible according to the compact construction requirements, providing more construction margins for the subsequent adjustment of various professional construction parameters.

[0061] Specifically, in this embodiment, the initial construction parameters are optimized by the equipment optimization parameters in the compact construction requirements to obtain the first construction parameters, including:

[0062] Obtaining device dimension data, air clearance data, and anti-magnetic shielding data of the initial construction parameters;

[0063] Obtaining corresponding size optimization parameters, air clearance optimization parameters and anti-magnetic optimization parameters from the compact construction requirements according to the equipment size data, the air clearance data and the anti-magnetic shielding data;

[0064] The device size data, the air clearance data and the anti-magnetic shielding data are optimized according to the size optimization parameter, the clearance optimization parameter and the anti-magnetic optimization parameter respectively to obtain the first construction parameter.

[0065] In order to improve the accuracy of the first construction parameters, the construction method provided by the present invention optimizes the initial construction parameters from three aspects: device size data, air clearance data, and anti-magnetic shielding data of the initial construction parameters. By matching the corresponding size optimization parameters, clearance optimization parameters, and anti-magnetic optimization parameters in the compact construction requirements, the device size data, air clearance data, and anti-magnetic shielding data are optimized respectively to ensure that the first construction parameters meet the compact construction requirements, and at the same time, the compact construction accuracy and effectiveness of the optimized first construction parameters can be effectively improved.

[0066] Furthermore, this embodiment optimizes the device size data, the air clearance data, and the anti-magnetic shielding data to obtain the first construction parameters, including:

[0067] Parsing the equipment size data to obtain converter valve data, connection transformer data and DC field data;

[0068] The converter valve data, the connection variable data and the DC field data are optimized respectively by using the size optimization parameters to obtain a first converter valve parameter, a first connection variable parameter and a first DC field parameter;

[0069] The first converter valve parameter, the first connection variable parameter and the first DC field parameter are integrated into the first construction parameter to update the first construction parameter.

[0070] When optimizing the equipment size data, the optimization method provided by the present invention is to optimize the converter valve data, connection transformer data and DC field data in the equipment size data respectively by obtaining the size optimization parameters required by the compact construction. Since the above three types of equipment occupy a large area, the optimization of the equipment size can be simplified to optimizing the arrangement of the above three types of equipment, so as to reduce the floor space of the equipment, improve the equipment size optimization effect and ensure that the parameters meet the compact construction requirements.

[0071] In this embodiment, when optimizing the parameters of the converter valve equipment, first, the aspect ratio of the valve tower can be adjusted according to the site size to improve the site utilization rate. For example, when the site is long and narrow, the converter valve is made into a single row to reduce the site width; otherwise, the converter valve layout is set to a double row layout according to the conventional design. Secondly, it is possible to consider increasing the number of layers in the height direction of the power module, such as setting the power module height to 5 layers to reduce the footprint of the unit power module. Thirdly, the number of valve towers on a single bridge arm can be minimized to reduce the footprint of the converter valve. For example, when the converter valve tower is 500kV, the total number of power modules in a single bridge arm remains unchanged, and can be constructed as 2 or 3 valve towers. Since 2 valve towers occupy less space, they are more suitable for compact layout.

[0072] When optimizing the parameters of the connecting transformer equipment, it is first necessary to determine the cooling method of the connecting transformer according to the compact construction requirements of the converter station, including air cooling (ODAF / OFAF), water cooling (OFWF / ODWF) or self-cooling (ONAN+ONAF+ODAF). Different optimization methods can be used for different cooling methods. When the cooling method is air cooling, the radiator occupies a medium size; when the cooling method is water cooling or self-cooling, the overall layout or separate layout can be selected according to the actual site to better adapt to the size of the site. Specifically, when the cooling method is water cooling, the radiator generally occupies a similar area to air cooling and the noise is usually smaller; when the cooling method is self-cooling, the radiator generally occupies a larger area. Therefore, in order to adapt to the compact construction requirements, this embodiment preferably adopts a cooling method that considers air cooling or water cooling, and if there are strict requirements on the noise value, consider the water cooling cooling method.

[0073] When further optimizing the DC field equipment, since the DC field equipment of the existing flexible DC converter station is open equipment, insulation is achieved through air, and related GIS products suitable for DC, namely gas insulated switchgear (GAS insulated SWITCHGEAR, referred to as GIS), are developed, generally using SF6 gas insulation. Therefore, this embodiment preferably selects compact DC GIS equipment according to the DC field data, namely the actual data of the converter station project, which can effectively save land.

[0074] Furthermore, this embodiment optimizes the device size data, the air clearance data, and the anti-magnetic shielding data to obtain the first construction parameters, including:

[0075] Screening the air clearance data to obtain limited position data;

[0076] Performing a simulation discharge experiment on the limited position data according to the gap shape optimization parameter and the insulation optimization parameter in the clearance optimization parameter to obtain a simulation experiment result;

[0077] A corresponding first gap parameter and a first insulation parameter are determined according to the simulation experiment result, and the first gap parameter and the first insulation parameter are integrated into the first construction parameter to update the first construction parameter.

[0078] When considering optimizing the air clearance data, since the air clearance is generally calculated based on the insulation level of each electrical device, the construction method provided by the present invention is to optimize the gap shape and insulation level of the limited position data in the air clearance data. The limited position data is simulated by the gap shape optimization parameters and insulation optimization parameters included in the compact construction requirements, and then the first gap parameter and the first insulation parameter that can better reduce the air clearance data are selected according to the obtained simulation results and integrated into the first construction parameters to improve the optimization effect of the air clearance data while ensuring that the parameters meet the compact construction requirements.

[0079] In this embodiment, when optimizing the air clearance data, the compact construction requirements can be considered. For the restricted layout positions in the air clearance data, i.e., the limited position data, a discharge simulation experiment is performed using specific insulation levels, i.e., insulation optimization parameters, and different discharge gap shapes, i.e., gap optimization parameters. The optimized air clearance value is determined in combination with the simulation experiment results. Specific parameters of the gap shape can also be set for the equipment during optimization to reduce the value of the air clearance and reduce the layout size.

[0080] Based on the same optimization method as the above optimization step, this embodiment optimizes the device size data, the air clearance data and the anti-magnetic shielding data to obtain the first construction parameters, including:

[0081] Performing simulation calculation on the anti-magnetic shielding data according to the anti-magnetic optimization parameters to obtain simulation calculation results;

[0082] A corresponding first anti-magnetic parameter is determined according to the simulation calculation result, and the first anti-magnetic parameter is integrated into the first construction parameter to update the first construction parameter.

[0083] In order to improve the anti-magnetic shielding effect of the construction parameters while ensuring that the construction parameters meet the compact construction requirements, the present invention will conduct simulation experiments on the anti-magnetic shielding data according to the anti-magnetic optimization parameters in the compact construction requirements, and select the first anti-magnetic parameter that can better improve the anti-magnetic shielding effect according to the simulation experiment results and integrate it into the first construction parameter to improve the optimization effect of the anti-magnetic shielding data while ensuring that the parameters meet the compact construction requirements.

[0084] In this embodiment, since the anti-magnetic range of the reactor has a great influence on the size of the room, when optimizing the anti-magnetic shielding data, it can be considered to combine simulation calculations and adopt special anti-magnetic shielding measures such as metal shielding to reduce the anti-magnetic range of the reactor, thereby effectively reducing the room size of the reactor room.

[0085] Step 103: optimizing the first construction parameters in sequence through preset hydraulic and HVAC construction parameters, structural and architectural construction parameters, and general layout construction parameters to obtain general construction parameters.

[0086] After the initial construction parameters are optimized according to the equipment optimization parameters to obtain the first construction parameters, the first construction parameters can be constructed and adjusted in turn according to the hydraulic HVAC construction parameters and the structural building construction parameters, that is, the electrical equipment corresponding to the layout parameters is added on the basis of the first construction parameters. After the layout of all equipment is completed, the construction parameters for the layout of all electrical equipment are integrated into the overall construction parameters through the general diagram construction parameters, that is, the overall layout plan of the entire converter station is formed through the general diagram construction parameters.

[0087] Specifically, this embodiment constructs the first construction parameters in sequence through preset hydraulic HVAC construction parameters, structural building construction parameters and general plan construction parameters to obtain the overall construction parameters, including:

[0088] Optimizing and constructing the first construction parameter according to the hydraulic HVAC construction parameter to obtain a second construction parameter;

[0089] Comparing the second construction parameter with the compact construction requirement to obtain a first comparison result;

[0090] When the first comparison result is that the second construction parameter meets the compact construction requirement, the second construction parameter is optimized and constructed by using the structural building construction parameter and the general plan construction parameter to obtain the general construction parameter.

[0091] In order to ensure that the optimized construction parameters meet the compact construction requirements, the construction method provided by the present invention will judge whether the second construction parameter meets the compact construction requirements after obtaining the second construction parameter from the first construction parameter through the hydraulic and HVAC construction parameters, that is, compare it with the compact construction requirements, and determine whether it meets the compact construction requirements based on the first comparison result. Only on the premise that it is determined that it meets the compact construction requirements, will the second construction parameter be adjusted through the structural building construction parameters and the general plan construction parameters to achieve multi-professional collaborative optimization of the converter station construction parameters, including electrical equipment and hydraulic and HVAC.

[0092] Furthermore, in this embodiment, the second construction parameter is optimized and constructed by using the structural building construction parameter and the general plan construction parameter to obtain the general construction parameter, including:

[0093] The second construction parameter is optimized by the structural building construction parameter to obtain a third construction parameter;

[0094] Comparing the third construction parameter with the compact construction requirement to obtain a second comparison result;

[0095] When the second comparison result is that the third construction parameter meets the compact construction requirement, the third construction parameter is optimized and constructed by using the overall construction parameter to obtain the overall construction parameter.

[0096] In order to further ensure that the optimized construction parameters meet the compact construction requirements, the construction method provided by the present invention will also judge whether the third construction parameter meets the compact construction requirements after the second construction parameter is constructed and adjusted through the structural building construction parameter, that is, it will be compared with the compact construction requirements. Only when it is determined that it meets the compact construction requirements can the next construction adjustment be made to further ensure that the adjusted optimized construction parameters meet the compact construction requirements, and at the same time, it can also achieve coordinated optimization between the structural building profession, the electrical equipment profession, and the hydraulic and HVAC profession.

[0097] Furthermore, in this embodiment, the third construction parameter is optimized and constructed by using the overall diagram construction parameter to obtain the overall construction parameter, including:

[0098] The third construction parameter is optimized and constructed by using the overall construction parameter to obtain a fourth construction parameter, and the fourth construction parameter is output as the overall construction parameter.

[0099] After optimizing and adjusting the construction parameters of the converter station through the above-mentioned specialties, the basic outline diagram of the construction parameters of the converter station can be determined, and then the third construction parameters optimized and adjusted by the above-mentioned specialties can be adjusted through the general diagram construction parameters to obtain the optimized overall construction parameters of the converter station.

[0100] Step 104: judging the total construction parameters according to the compact construction requirements, and when it is determined that the total construction parameters meet the compact construction requirements, outputting the total construction parameters as a construction scheme, and constructing the target flexible DC converter station according to the construction scheme.

[0101] After obtaining the total construction parameters, the total construction parameters will be judged according to the compact construction requirements to determine whether the total construction parameters meet the compact construction requirements, such as whether the available site area is met and whether the site utilization rate reaches the preset standard utilization rate. Only when it is determined that the total construction parameters meet the compact construction requirements can the total construction parameters be output as a determined construction plan, and the target flexible DC converter station can be constructed according to the construction plan.

[0102] Specifically, this embodiment determines the total construction parameter according to the compact construction requirement, and further includes:

[0103] When it is determined that the total construction parameters do not meet the compact construction requirements, the compact construction requirements are adjusted according to the total construction parameters, and the process returns to generating the initial construction parameters according to the electrical equipment construction data and the converter station data.

[0104] When judging the compact construction requirements for the total construction parameters, if the judgment result is that the total construction parameters do not meet the compact construction requirements, it is necessary to return to the step of generating the initial construction parameters based on the electrical equipment data and the converter station data. At the same time, the compact construction requirements will be adjusted according to the generated total construction parameters to improve the accuracy of the subsequent optimization adjustment of the initial construction parameters by various disciplines according to the compact construction requirements.

[0105] The construction method provided in the embodiment of the present invention first obtains the converter station data and compact construction requirements of the target flexible DC converter station, that is, obtains the basic data of the converter station that needs to be compactly constructed and the basic requirements for compact construction of the converter station. After determination, the initial construction parameters of the converter station are generated according to the electrical equipment construction data and the converter station data, that is, the construction parameters of the electrical equipment functional room of the converter station are generated, and after generation, the initial construction parameters are optimized for the first time through the equipment optimization parameters to obtain the first construction parameters to improve the accuracy of the first construction parameters. The first construction parameters are optimized through the hydraulic HVAC construction parameters, the structural building construction parameters and the general drawing construction parameters to further improve the accuracy of the total construction parameters. Then, according to the compact construction requirements, it is judged whether the total construction parameters meet the requirements to ensure the effectiveness and practicality of the total construction parameters. Only when it is judged that it meets the requirements will it be output as a construction plan and the target flexible DC converter station is constructed according to the output construction plan. The present invention collaboratively optimizes the construction parameters of the converter station through various professions, including electrical equipment, hydraulic HVAC, structural architecture and general layout construction, and makes a compact judgment on the overall construction parameters after optimization, which can effectively improve the accuracy and practicality of the compact construction plan of the converter station.

[0106] Embodiment 2

[0107] For a more detailed description of the construction method provided by the present invention, see Figure 3 , Figure 3 The flowchart of another embodiment of the method for constructing a flexible DC converter station provided by the present invention is as follows. Figure 3 As shown, compared with the first embodiment, the process provided in this embodiment is more detailed, and this embodiment is more specific in terms of the construction parameters, i.e. Figure 3 When the layout scheme shown is used to determine the compact construction requirements, the layout scheme is compared with the electrical equipment layout to determine whether the layout scheme collides with the electrical equipment. In this embodiment, the structural building parameters are divided into two majors, structure and architecture, and the layout scheme is optimized and adjusted through the two parameters. The specific steps of this embodiment are as follows:

[0108] The first step, electrical equipment room design, refers to the electrical professional constructing the parameters of the electrical equipment functional room, that is, constructing the parameters of the electrical functional room for the initial data of the converter station through the electrical professional parameters, and reducing the size of the functional room by optimizing the equipment size, air clearance, anti-magnetic shielding and other measures during the parameter construction process, and then optimizing the maintenance and installation space in combination with the maintenance and installation conditions.

[0109] Similar to the construction method provided in the first embodiment, this embodiment optimizes the construction data of the electrical function room by optimizing the equipment size, air clearance, and anti-magnetic shielding measures. When optimizing the equipment size, the parameters of the converter valve, the connecting transformer, and the DC field equipment are also optimized.

[0110] In addition, compared to the first embodiment, this embodiment will also optimize the maintenance and installation space when optimizing the construction data of the electrical function room. The actual space required can be verified in combination with the specific maintenance and installation conditions of each equipment to optimize the room size.

[0111] In the second step, the electrical equipment rooms are connected in combination with the process flow to form a multi-layer indoor electrical layout plan. Specifically, the electrical professional parameters are used to connect and arrange the functional rooms of various electrical equipment according to the electrical process flow of the converter station. It is preferred to adopt a multi-layer layout to reduce the floor space of the converter station, thereby forming an indoor multi-layer electrical layout plan, which is the first construction parameter in Example 1.

[0112] The third step is hydraulic and HVAC design, which refers to the construction of converter station auxiliary system parameters for the indoor multi-layer layout plan formed in the second step based on hydraulic and HVAC professional parameters. During the construction process, the air-conditioning cooling capacity is optimized according to the needs of the equipment function room, the converter valve cooling system configuration is optimized, and various HVAC and hydraulic pipelines are arranged in a compact manner to achieve coordinated optimization with the construction of related electrical function rooms.

[0113] Moreover, when HVAC equipment or hydraulic pipeline equipment conflicts with electrical equipment, the HVAC professional parameters or hydraulic professional parameters need to be adjusted to the corresponding conflicting equipment or pipeline positions to avoid collision and meet the clearance requirements of electrical equipment, so as to improve the coordinated optimization effect of electrical equipment and hydraulic HVAC equipment.

[0114] The fourth step, structural design, refers to the coordinated optimization of the structural and electrical function room parameter construction, which specifically includes the selection of structural systems and the verification of seismic performance. During the parameter construction process, when the structural columns or beams conflict with the electrical equipment, or do not meet the live clearance requirements, the electrical and structural professionals need to work together to optimize and adjust. The stability of the structure can be achieved by fine-tuning the equipment position or adjusting the size or position of the structural columns while meeting the electrical process flow.

[0115] In addition, after completing the adjustment of the structural professional parameters, it will also be judged whether the layout of electrical equipment meets the seismic requirements. By analyzing the impact of multi-layer layout on the seismic energy of equipment, a floor acceleration response control method is established to optimize the selection of building structure system. When it is determined that the layout of electrical equipment does not meet the seismic requirements, the equipment needs to be adjusted in combination with the structural construction requirements, such as: arranging the equipment that does not meet the seismic requirements on the lower floors, or adding shock-absorbing pads and other measures, or asking the equipment manufacturer to build according to the seismic requirements of the structure.

[0116] In the fifth step, the architectural profession optimizes fire passages and fire zones, conducts facade design, and provides a building design plan. This means that the architectural profession optimizes the fire passages and fire zones of the building based on the electrical layout plan output in the fourth step, conducts building facade construction, and forms an indoor flexible DC converter station building construction plan to improve the construction parameters.

[0117] The sixth step is to design the station front area and roads according to the general plan to form a general layout plan for the converter station. This means that after the construction of various professional parameters is completed, the architectural appearance of the overall converter station is basically determined. Then, the general plan professional parameters are required to construct the parameters of the station front area, station area fence, entrance and station roads based on the indoor flexible DC converter station building construction plan to form a general layout plan for the indoor flexible DC converter station, that is, the general construction parameters in Example 1.

[0118] After the general layout plan of the indoor flexible DC converter station is formed, in order to ensure that the layout plan meets the requirements of compact construction, it will also be judged whether the layout plan meets the site land requirements. If it does not meet the site land requirements, it is necessary for all professionals to work together to optimize the compressed plane footprint, and at the same time, the compact layout reasonably compresses the construction margin. If it still does not meet the land requirements, it is necessary to consider adding floors to reduce the site land, so as to iteratively correct the general layout plan until the site land requirements are met.

[0119] The seventh step is to output the overall layout plan of the indoor multi-layer flexible DC converter station, complete the optimization adjustment of the construction parameters of the flexible DC converter station, and build the target converter station according to the output construction plan.

[0120] This embodiment uses multi-professional collaborative construction optimization to continuously iterate and correct the overall layout construction plan, reduce the land area of ​​the flexible DC converter station, meet the land demand for the construction of urban indoor flexible DC converter stations, and improve the multi-professional collaborative system optimization effect on the construction parameters of the flexible DC converter station.
