Description

Technical Field

[0001] The present invention relates to the field of direct current power transmission technology, and in particular to a comprehensive temperature control method, system and storage medium for a direct current valve hall and a converter valve. Background Art

[0002] The DC valve hall is an important component of the HVDC transmission system, mainly used to accommodate and control key equipment such as DC converter valves. These devices play a vital role in the DC transmission process, responsible for converting AC to DC, or converting DC back to AC. The internal operating temperature of the DC valve hall has an important impact on the performance and stability of the entire system. The equipment in the valve hall will generate a lot of heat during operation. If the temperature is too high, it will not only affect the performance of the equipment, but may also cause failures. Therefore, effective temperature control measures must be taken to ensure that the temperature in the valve hall remains within an appropriate range.

[0003] The traditional temperature control method is to achieve normal operation of the internal equipment of the DC valve hall by adjusting the temperature of the converter valve equipment and the indoor temperature of the DC valve hall respectively.

[0065] For the DC valve hall, firstly, a basic DC valve hall thermal-fluid coupling field simulation model is constructed according to the physical structure of the DC valve hall, HVAC equipment drawings, converter valve equipment drawings and other information; then, based on the historically collected data such as the DC valve hall indoor temperature, DC valve hall outdoor temperature, converter valve temperature, HVAC equipment output power, HVAC equipment carbon emissions, etc., combined with the basic DC valve hall thermal-fluid coupling field simulation model, the DC valve hall thermal-fluid coupling field simulation calculation is carried out; finally, the DC valve hall thermal-fluid coupling field simulation data and the actual temperature data change curve are compared to adjust the parameters such as the thermal conductivity coefficient, convection coefficient, and carbon emissions to improve the accuracy of the DC valve hall thermal-fluid coupling field simulation model, and the DC valve hall thermal-fluid coupling field simulation model with improved accuracy is obtained.

[0066] As one of the optional embodiments, if the thermal-fluid coupling field simulation model is the thermal-fluid coupling field simulation model of the converter valve, then the simulation based on the basic thermal-fluid coupling field simulation model is performed using the historical operation data of the DC valve hall and the converter valve to obtain the simulation results, including:

By adjusting the outdoor temperature of the DC valve hall, the indoor air-conditioning temperature of the DC valve hall and the converter valve temperature, time domain curve data of the indoor temperature of the DC valve hall and the converter valve temperature are obtained through simulation.

[0072] It should be noted that the convection heat exchange boundary conditions on the surface of the converter valve structure are obtained by using computational fluid dynamics and finite element analysis technology to simulate the thermal-fluid coupling field of the converter valve; and the convection heat exchange boundary conditions of the DC valve hall are obtained by using computational fluid dynamics and finite element analysis technology to simulate the thermal-fluid coupling field of the DC valve hall.

[0073] S2: obtaining current operating data of the DC valve hall and the converter valve, and inputting the current operating data into a preset temperature prediction model to obtain future temperature trends of the DC valve hall and the converter valve; wherein the temperature prediction model is trained based on historical operating data of the DC valve hall and the converter valve;

[0074] As one of the optional embodiments, the current operating data includes: indoor temperature of the DC valve hall, outdoor temperature of the DC valve hall, indoor air-conditioning temperature of the DC valve hall, operating current and voltage values ​​of the converter valve, converter valve temperature, condensate flow rate of the converter valve, condensate outlet and inlet temperature of the converter valve, condensate outlet and inlet temperature outside the valve, and at least one of the output power of the HVAC equipment.

[0075] As one of the optional embodiments, the preset temperature prediction model is a long short-term memory model; in the long short-term memory model, the converter valve temperature, the converter valve condensate flow, the DC valve hall indoor temperature, the HVAC equipment output power and the DC valve hall outdoor temperature are used as neurons.

[0076] Specifically, the temperature prediction model can predict the temperature trend of the converter valve and the DC valve hall in the future based on the current actual operation data.

[0077] S3: Based on the thermal-fluid coupling field simulation model of the converter valve and the thermal-fluid coupling field simulation model of the DC valve hall, according to the future temperature trend and the current operating data, under the condition that the temperature of the converter valve does not exceed the limit, an ant colony algorithm is used to generate comprehensive temperature control schemes for multiple converter valves and DC valve halls, and with the goal of minimizing the carbon emissions of the comprehensive temperature control scheme, the optimal comprehensive temperature control scheme is obtained by solving the optimization algorithm.

[0078] Specifically, by using the thermal-fluid coupling field simulation model of the converter valve and the thermal-fluid coupling field simulation model of the DC valve hall with improved accuracy, according to the current indoor and outdoor temperatures of the DC valve hall, the operating current and voltage values ​​of the converter valve, and combined with the future temperature trends of the converter valve and the DC valve hall, on the premise that the operating temperature of the converter valve does not exceed the limit, the ant colony algorithm is used to generate a variety of comprehensive temperature control schemes for the converter valve and the DC valve hall to reduce the indoor air-conditioning temperature of the DC valve hall and increase the condensate flow rate of the converter valve, and the carbon emissions of the corresponding schemes are calculated. Then, the optimization algorithm is used to solve the optimal comprehensive temperature control scheme for the converter valve and the DC valve hall with the goal of minimizing carbon emissions. For example: by increasing the condensate flow rate of the converter valve by 1L / s, the carbon emissions of the cooling water system outside the valve will be increased, and the output temperature of the HVAC system will be increased by 1°C (i.e. the indoor air-conditioning temperature of the DC valve hall), thereby reducing the carbon emissions of the HVAC equipment; or reducing the condensate flow rate of the converter valve by 1L / s, reducing the carbon emissions of the cooling water system outside the valve, and lowering the output temperature of the HVAC system by 1°C, thereby increasing the carbon emissions of the HVAC equipment; achieving comprehensive control of the temperature of the converter valve and the DC valve hall, while reducing the carbon emissions generated by the temperature control of the converter valve and the DC valve hall.

[0079] As one of the optional embodiments, the carbon emissions of the comprehensive temperature control solution include:

[0080] Carbon emissions from the cooling water system outside the valve when the converter valve temperature drops to normal, and carbon emissions from the HVAC equipment when the indoor temperature of the DC valve hall drops by 1°C.

[0081] As one of the optional embodiments, the carbon emissions of the cooling water system outside the valve when the temperature of the converter valve is reduced to a normal value CDE FWL The calculation formula is:

[0082] CDEFWL =F FWL ·V(T CUR -T NOR )μ in ·μ out ;

[0083] Among them, F FWL is the energy consumption of cooling the condensed water in the valve for 1 unit flow rate; V is the condensed water flow rate of the converter valve corresponding to a 1°C decrease in the converter valve temperature; T CUR is the current converter valve temperature; T NOR is the normal value of the converter valve temperature; μ in is the indoor temperature influence coefficient; μ out is the outdoor temperature influence coefficient;

[0084] The carbon emissions of HVAC equipment when the indoor temperature of the DC valve hall is reduced by 1°C CDE NT The calculation formula is:

[0085] CDE NT =F NT ·μ out ;

[0086] Among them, F NT μ is the HVAC energy consumption caused by reducing the indoor temperature of the DC valve hall by 1°C; out is the outdoor temperature influence coefficient.

[0087] Specifically, by calculating the temperature value that the converter valve needs to be lowered, combined with the indoor temperature influence coefficient and the converter valve condensate flow rate corresponding to the converter valve temperature being reduced by 1°C, the converter valve condensate flow rate V when the current converter valve equipment is cooled to the normal value is obtained. HLF :

[0088] V HLF =V·(T CUR -T NOR )·μ in ;

[0089] Where V is the condensate flow rate of the converter valve corresponding to a 1°C decrease in the converter valve temperature; T CUR is the current converter valve temperature; T NOR is the normal value of the converter valve temperature; μ in is the indoor temperature influence coefficient.

[0090] Furthermore, by calculating the total energy consumption of cooling water outside the valve and combining the outdoor temperature influence coefficient, the carbon emissions CDE of the cooling water system outside the valve when the converter valve temperature drops to the normal value is calculated. FWL :

[0091] CDE FWL =F FWL ·VHLF ·μ out ;

[0092] Among them, F FWL V is the energy consumption for cooling the condensed water in the valve per unit flow rate; HLF The condensate flow rate of the converter valve when the converter valve equipment is cooled to the normal value; μ out is the outdoor temperature influence coefficient.

[0093] It should be noted that the outdoor temperature of the DC valve hall and the outdoor temperature influence coefficient μ out Positive correlation, the lower the outdoor temperature of the DC valve hall, the greater the outdoor temperature influence coefficient μ out The smaller the temperature, the smaller the carbon emissions. The carbon emissions generated by the HVAC equipment for cooling the indoor temperature of the DC valve hall changes in a sinusoidal manner according to the increase and decrease of the outdoor temperature of the DC valve hall. The carbon emissions generated by the valve external cooling water system for cooling the condensed water of the converter valve changes in a sinusoidal manner according to the increase and decrease of the outdoor temperature of the DC valve hall. By analyzing and comparing the carbon emission change curves of the outdoor temperature of the DC valve hall and the HVAC equipment and the valve external cooling water system, the carbon emission growth trend of the HVAC equipment and the valve external cooling water system in different outdoor temperature ranges can be obtained according to the curve change rate, and this can be used as a reference condition for optimizing the comprehensive temperature control scheme of the converter valve and the DC valve hall.

[0094] DC valve hall indoor temperature and indoor temperature influence coefficient μ in Positive correlation, the lower the indoor temperature of the DC valve hall, the greater the indoor temperature influence coefficient μ in The smaller the value, the smaller the condensate flow of the converter valve changes in a sinusoidal manner according to the increase and decrease of the indoor temperature of the DC valve hall.

[0095] Since the converter valve operating temperature (i.e. converter valve temperature) and the DC valve hall indoor temperature (i.e. DC valve hall temperature) affect each other, if the converter valve operating temperature is too high, the DC valve hall indoor temperature rise speed will be accelerated, the HVAC equipment output power will increase, and the HVAC equipment will generate an increase in carbon emissions for cooling the DC valve hall indoor temperature; if the DC valve hall indoor temperature is too high, the condensed water in the valve and the converter valve temperature replacement efficiency will be slowed down, the condensed water flow in the valve will increase, and the valve external cooling water system will generate an increase in carbon emissions for cooling the condensed water in the valve.
