Description

Technical Field

[0001] The present invention relates to the technical field of electric power dispatching, and in particular to a method for collecting and calculating electric power data of a non-centrally dispatched power supply. Background Art

[0002] The full-caliber power supply is an important parameter that reflects the changing characteristics of power demand in a region. The stable change of its data is an important reference indicator for the safe and reliable operation of the power dispatching and control system. The full-caliber power supply is divided into two categories: centralized power supply and non-centrally dispatched power supply. The centralized power supply refers to the transmission and transformation equipment of the generator set, which is managed by the power generation enterprise and dispatched by the power grid enterprise; the non-centrally dispatched power supply mainly refers to the self-contained power plants, distributed wind farms, photovoltaic power stations, and small hydropower facilities connected to the 10kV and below distribution network. These power sources are not included in the unified dispatch of the power grid enterprise due to the small capacity of a single station. With the rapid growth of the installed capacity of distributed new energy represented by wind power and photovoltaic power, the proportion of non-centrally dispatched power supply has increased rapidly. The characteristics of wind power and photovoltaic power being greatly affected by weather changes make the power data of non-centrally dispatched power supply susceptible to weather and fluctuate rapidly. As the operation and maintenance resources invested by power generation companies to which non-centrally controlled power sources belong are very limited, they are usually not equipped with dedicated telecontrol devices and do not have conventional communication methods such as dedicated network lines. They usually use non-centrally controlled collection terminals with 4G network communications to collect and forward power data, or directly use line power data on the substation side of the grid to which they are connected instead of power data. The data reliability and stability are relatively insufficient.

[0003] With the development of lean power grid dispatching, the requirements for full-caliber power source power collection and monitoring coverage are becoming higher and higher. The existing power dispatching automation technology is mainly aimed at main power plants and substations. When applied to small plants and remote areas, it is difficult to simultaneously meet the requirements of small project investment, low construction and maintenance workload, and high information data security. In order to achieve stable and reliable power supply, it is of great significance to use the existing power dispatching automation platform and data communication channels to accurately, stably and safely transmit non-coordinated power source power data to ensure balanced power dispatching.

[0004] Therefore, it is necessary to design a power data acquisition and calculation method for non-coordinated power supply. Summary of the invention

[0005] The purpose of the present invention is to solve at least one of the technical problems existing in the prior art and to provide a method for collecting and calculating power data of a non-coordinated power supply.

[0006] To achieve the above object, the technical solution adopted by the present invention is as follows: a method for collecting and calculating power data of a non-coordinated power supply, comprising the following steps:

[0007] Step S1: Each non-centrally-regulated power concentrator collects active power sampling data from each electric energy meter in real time, processes and stores the data to obtain real-time active power data of the non-centrally-regulated power source;

[0008] Step S2: Each non-centrally-regulated power concentrator transmits the active power data of the non-centrally-regulated power source to the main station of the power consumption information collection system of the management information area in real time via the wireless public network and the boundary firewall between the power user power consumption information collection system and the wireless public network;

[0009] Step S3: The main station of the power consumption information collection system uses the Kafka system to transmit the active power data of the non-centrally controlled power supply to the data center and data transfer system in real time;

[0010] Step S4: The data transfer system uses the real-time active power data and the non-centrally controlled power source ledger information provided by the data center to filter and calculate the power data of non-centrally controlled power sources in each region, and sends the power data of non-centrally controlled power sources in each region to the provincial control cloud in real time, and transmits it to the control cloud real-time data platform of the production control area through the reverse physical isolation device of the control cloud I / III area;

[0011] Step S5: After the SCADA system of the production control area obtains the power data of non-centrally coordinated power sources in various regions forwarded in real time by the main station of the power consumption information collection system, it accumulates and calculates the power data of non-centrally coordinated power sources in various regions and the power data of non-centrally coordinated power sources directly collected from the dispatching data network to obtain the real-time data of the total power of non-centrally coordinated power sources in the dispatching range.

[0012] Furthermore, the non-centrally controlled power concentrator of step S2 includes a security protection module, which is used to encrypt information transmitted between the non-centrally controlled power concentrator and the main station of the power consumption information collection system through the wireless public network, and to perform identity recognition, security authentication, and secure transmission of key information and sensitive information between the concentrator and the electric energy meter.

[0013] Furthermore, the specific process of step S3 is as follows:

[0014] Step S301: Each non-centrally controlled power concentrator transmits active power data to the power consumption information collection system master station in real time;

[0015] Step S302: The main station of the power consumption information collection system publishes the active power data of the non-centrally coordinated power supply to the main station of the power consumption information collection system and the Kafka system of the data middle station in real time through the distributed Kafka system;

[0016] Step S303: The Kafka system of the data center is connected to the real-time database of the data center in real time, and a dedicated data transfer system is deployed to filter and process the real-time data of active power through the non-centrally controlled power supply ledger and user information.

[0017] Furthermore, the specific process of step S4 is as follows:

[0018] Step S401: The marketing management system synchronizes the non-centrally coordinated power supply ledger and user information to the power consumption information collection system master station via the information intranet horizontal domain boundary firewall;

[0019] Step S402: The main station of the power consumption information collection system pushes the non-centrally coordinated power supply account and user information to the DWS database of the data center synchronously;

[0020] Step S403: The data center provides API services to collect the previous day's non-centrally controlled power supply ledger and user information data to the provincial control cloud database, and update the data once a day;

[0021] Step S404: The data transfer system calculates and processes the active power data in real time, accesses the provincial control cloud through the firewall, and transmits it to the real-time data platform of the control cloud of the production control area through the reverse physical isolation device of zone I / III;

[0022] Step S405: The provincial control cloud collects real-time active power data and combines it with the non-centrally controlled power source account information data to calculate the real-time power data of non-centrally controlled power sources within the last 5 minutes every 2 minutes; and calculates the power frozen data of non-centrally controlled power sources within the last 2 hours every 5 minutes;

[0023] The calculation formula for the real-time data of non-centrally controlled power sources is:

[0024]

[0025] In the formula, Yes k The non-coordinated power supply at all times, Yes k The power of the jth non-centrally controlled power source in the i-th region at the moment, N is the number of regions within the control range, M i is the total number of non-coordinated power sources in the ith region;

[0026] Among them, the calculation formula for the power freeze data of non-centrally coordinated power sources is:

[0027]

[0028] In the formula, Yes k The non-coordinated power supply at all times, Yes k The power of the jth non-centrally controlled power source in the i-th region at the moment, N is the number of regions within the control range, M i is the total number of non-coordinated power sources in the ith region;

[0029] Step S406: The provincial control cloud generates an E file based on the calculated real-time data of power from non-centrally controlled power sources, and pushes the file to the D5000 system every minute;

[0030] Step S407: The D5000 system parses the E file to obtain the power data of the non-centrally coordinated power sources in each region and forwards it to the SCADA system in real time.

[0031] Furthermore, the specific process of step S5 is as follows:

[0032] Step S501: The SCADA system obtains the real-time power data of the non-centrally controlled power source forwarded by the power consumption information collection system master station;

[0033] Step S502: The non-centrally-regulated power source that meets the conditions for direct sampling from the dispatching data network performs high-precision sampling of the power of the non-centrally-regulated power source through the measurement and control device, and transmits the sampling to the 35kV dispatching data network in real time through the telecontrol device and the longitudinal encryption device;

[0034] Step S503: The front steady-state data acquisition server of the ground dispatching D5000 system collects the direct power acquisition data of the non-centrally dispatched power source transmitted by the dispatching data network in real time and forwards it to the SCADA system;

[0035] Step S504: The SCADA system accumulates the real-time data of non-centrally controlled power sources forwarded by the power consumption information collection system master station and the non-centrally controlled power sources collected by the front-end steady-state data collection server of the ground control D5000 system to obtain the real-time data of the total power of non-centrally controlled power sources within the control range.

[0036] It can be seen from the above description of the present invention that, compared with the prior art, the non-coordinated power supply power data acquisition and calculation method of the present invention includes at least one of the following beneficial effects:

[0037] 1. The present invention collects and calculates the power of non-centrally controlled power sources through power consumption information collection and control cloud interaction. Since the power consumption information collection system is an important data source for power settlement, the power generation enterprises to which the non-centrally controlled power sources belong can give priority to guaranteeing the investment of power supply energy meters and concentrator operation and maintenance resources, and give priority to ensuring the safe and stable operation of these devices, effectively ensuring the real-time and stability of power consumption data transmission;

[0038] 2. Although the power data collected by the present invention is transmitted through the wireless public network, the system boundary, network, host / server are protected, which can effectively eliminate the breakpoint problem of power data collected and forwarded by the non-centrally coordinated power generation data collection terminal of 4G network communication in the D5000 direct collection and forwarding data. At the same time, it can avoid using the power data of the grid-side substation to replace the power data of the non-centrally coordinated power supply, thereby ensuring the reliability of the power data source of the non-centrally coordinated power supply;

[0039] 3. The power data of the non-centrally controlled power supply of the present invention originates from the power consumption information collection system. The power data obtained through the wireless public network originates from the concentrator equipped with a security protection module, and is connected to the main station of the power consumption information collection system of the management information area through the firewall device, and is connected to the production control area SCADA system through the provincial control cloud I / III area horizontal physical isolation device. The entire power data collection and transfer process is within the existing network security protection system, which ensures the security of the power data source and data transmission of the non-centrally controlled power supply.
