Application Of Relay Protection Fault Information System In Baoshan Power Grid

With the gradual expansion of the scale of Baoshan power grid, the grid structure is becoming more and more complex. When the power grid is in trouble, it is more difficult to deal with the faults. Relay protection fault information system can realize the effective record and analysis of the operation condition, setting value, action, recorded wave and switch quantity, etc., from the point of view of the whole power grid, the judgment of the protection action, is a developing direction of intelligent dispatching.Aiming at the existing problems in Baoshan, Yunnan power grid 220kV Baoshan, 220kV Chaoyang, Tengchong 220kV transformer,220kV Huanglong,220kV Shidian, 220kV Changning, it is pointed out that the necessity of the establishment of the information management system of relay protection. The overall design of the system structure of the fault information system in Baoshan power network is designed. At the same time, the distributed and heterogeneous system is built according to the structure, function and technical index of the fault information system of relay protection in Baoshan power network. The system supports various applications, maintenance free, and compatible with the existing automation system. The problem of meeting the two security requirements in the construction of the security sub-station is discussed, and the data network of Baoshan electric power dispatching data network is established. System construction has positive significance for improving the safety and reliability of the operation of Baoshan power network.
