Abstract

The invention provides a real-time monitoring method of a power system. The method comprises the following steps that S1) a base station end, a substation end connected to the base station end and a server end connected to both the base station end and the substation end are configured, and a unified model is established in the server end; S2) according to the model, a corresponding fault recording device and a potential measuring device are configured; S3) the fault recording device is used to start determination, when start exists, a fault file is generated, a transient fault and real-time data are recorded, and offline analysis of fault recording data is completed; S4) the main potential measuring device carries out remote measurement, remote signaling and remote control on electric energy data of the base station end and the substation end, and analyzes the data according to corresponding protocols; and S5) an analysis result is used to carry out topology analysis and state estimation on the base station end and the substation end of the power grid. The method can be used to monitor the dynamic process of the interconnected power grid in real time.

Description

technical field [0001] The invention belongs to the technical field of electric power, and in particular relates to a real-time monitoring method of an 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 ; 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...
