Provide a basis for the smart grid
“The application of electric energy meter and the access of automatic data acquisition device provide detailed and timely data loss support for the Baojia substation in the transformation. The electric energy meter after re-construction and debugging does not mention the intelligent word in the name. However, the function has completely realized the intelligence." Shen Yuguo, the stationmaster of Baojia Substation, said.
The power loss management of the Northeast Power Grid originally adopted the basic factory and station manual reporting method. Each factory and station operators reported the network loss report every month, and then the statistics were scheduled by each network. The implementation of the automatic collection system for the primary grid loss data of the Northeast Power Grid has newly added the data of the automatic collection of network loss data in Liao, Ji and Black provinces, which can realize the real-time calculation and statistics of the network loss, and grasp the network loss information and understanding for the grid in real time. The law of network loss changes and effective loss provides a scientific basis.
The Changchun Super High Voltage Bureau of the Northeast Power Grid needs to install metering electric energy meters for five substations. Among them, the 500 kV Baojia Substation is undergoing the renovation of intelligent substation. The data acquisition and access of a network loss power supply provides a basic platform for real-time data acquisition and analysis, online monitoring and control of Baojia Substation, which complements the transformation work of intelligent substation.
Shen Yuguo painted such a picture for the reporter - the future Baojia substation will be unattended, and the automatically collected data provides real-time online monitoring, control and service for the operation of the intelligent substation.
Lean management takes a solid step
The transformation of the Northeast Power Grid's data collection and access to the network's power loss will provide more accurate and reliable data analysis for grid loss and economic operation, and also provide lean management for the primary network's primary network loss grade and sub-region. Laid a solid foundation.
The automatic collection of network loss data has realized the data collection and standardized transmission of all billing and assessment points of Northeast Power Grid, providing effective real-time data of network loss for production, scheduling, finance and other departments, realizing automatic and accurate calculation of network loss. .
Northeast Electric Power Grid Co., Ltd. gradually realized the significance of this work in the process of automatic collection and access of network loss data. The Northeast Power Grid has a wide range of lines. In the process of building a smart grid, the implementation of this project will not only make the data more timely and accurate, but also classify and analyze the data while collecting data and accessing data. Northeast Power Grid provides a detailed and powerful decision-making basis, which is also a solid step taken by Northeast Power Grid Co., Ltd. on the path of lean management.

Before the implementation of the automatic collection of power loss data, the factories and station workers of Northeast Power Grid Co., Ltd. can only read the meter on site, and are responsible for finding a single piece of data in a large number of papers. The workload is large, the data is complicated and inevitable errors; After the real-time automatic acquisition of the loss data, it is possible to accurately analyze the data and calculate the network loss based on the data collected in real time, which provides reliable data and technical support for more effective reduction of network loss and improvement of efficiency.
The biggest feeling of giving the dispatch center the responsibility after the system transformation is to save time and effort. “The power collection device runs stably, the data collection is efficient and accurate, and it has the function of automatic data verification. It saves the on-site meter reading of the factory and station workers, saves the manual entry of the meter reading data, and saves the manual report. Supervise and save the verification of the artificially reported data." The network loss and measurement of the Northeast Network is responsible for describing the feelings of the new system. In this way, the special responsibility can put more energy and time on how to analyze the data and reduce the network loss.
In addition, the automatic acquisition device has intelligent self-healing function, which can recover itself in case of failure, ensuring uninterrupted and reliable operation and greatly improving the stability of the system. Specialists no longer have to worry about losing data after a system failure.
