Abstract

The invention provides a real time monitoring system for electric power system. The monitoring system comprises a base station terminal, sub-station terminals in connection with the base station terminal, and a server terminal in connection with the base station terminal and the sub-station terminals respectively. The server is provided with a uniform model therein. Based on the model, a fault wave recording device and an electric potential measuring device are configured correspondingly. Through the use of the fault wave recording device, it is possible to determine whether to start the monitoring system or not; when the monitoring system is started, a document on fault is generated in which transient fault and real-time data are recorded and offline analysis on the recorded wave data is completed. A main electric potential measuring device is utilized to remotely measure, telemeter and control the power data of the base station terminal and the sub-station terminals and analyzes the data according to a corresponding protocol. Based on the analyzing result, the server conducts topology analysis and state estimation of the base station terminal and the sub-station terminals of a power grid. The system of the invention is capable of achieving real time monitoring on the dynamic process of interconnected power grids.

Description

technical field [0001] The invention belongs to the technical field of electric power, in particular to a real-time monitoring of electric power system. Background technique [0002] At present, with the continuous development of my country's electric power industry, it is urgent to change the current situation of 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 provide timely and accurate guarantee for user decision-making in the data integration and information exchange between IED equipment, but it only sends data to the master station in the event of a fault, and cannot monitor the operating status of the power system. Monitoring: Synchronized phasor 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, which does not reflect th...
