Integrated monitoring system of power system operating condition

Abstract

A system for comprehensively monitoring the running state of power system comprises a data information acquisition module, a data exchange processing module, a host computer and a monitoring general control room which are sequentially connected. The data exchange processing module comprises a sub-station end and a base station end. The data exchange processing module comprises a processor and a server. A unified model is established in the server. According to the unified model, a corresponding fault recording device and a main potential measuring device are configured. The invention not onlyrealizes the data recording under the condition of power system fault, but also realizes the data recording under the condition of power system fault, synchronous phasor measurement is also realized for important substations and substations of power system, Furthermore, a real-time dynamic monitoring system of the power system is constructed to strengthen the monitoring of the dynamic safety and stability of the power system and improve the ability of the commissioning mechanism to accurately grasp the running state of the system. The invention can be customized flexibly, has various functions, is high in maintainability, and can be adapted to a standard protocol.

Description

technical field [0001] The invention relates to the technical field of power system detection, in particular to a comprehensive monitoring system for power system operation status. Background technique [0002] At present, with the continuous development of my country's electric power industry, it has become a top priority to change the repeated data collection of secondary equipment, lack of data integration and processing, and lack of information exchange and sharing. The existing wave recorder in the substation can be used between IED equipment In data integration and information exchange, it provides timely and accurate guarantee for user decision-making, but only sends data to the master station in case of failure, and cannot monitor the operating status of the power system; synchrophasor measurement can monitor the operating status of the system in real time , but the recorded data are only steady-state quantities, and the recording frequency is low, reflecting the real ...

[0002] At present, with the continuous development of my country's electric power industry, it has become a top priority to change the repeated data collection of secondary equipment, lack of data integration and processing, and lack of information exchange and sharing. The existing wave recorder in the substation can be used between IED equipment In data integration and information exchange, it provides timely and accurate guarantee for user decision-making, but only sends data to the master station in case of failure, and cannot monitor the operating status of the power system; synchrophasor measurement can monitor the operating status of the system in real time , but the recorded data are only steady-state quantities, and the recording frequency is low, reflecting the real situation of line faults is not good. At present, there is no unified modeling of fault recording and synchrophasor measurement with the same hardware platform according to the standard , to realize the real-time monitoring and recording system of the dynamic process of the interconnected power grid, and the existing power monitoring system has poor adaptability and scalability, and the system maintenance is cumbersome. After the system is abnormal, the data cannot be recovered, and the expansion and maintainability are poor.
