Real-time running status evaluation based power distribution network running risk warning system

Abstract

The invention discloses a real-time running status evaluation based power distribution network running risk warning system. The system comprises a power grid model and running mode acquisition module, a risk warning analysis module, a risk solution module and an analysis result display module, the power grid model and running mode acquisition module is used for acquiring a power grid model and a running mode from a power distribution network SCADA (supervisory control and data acquisition) system; the risk warning analysis module is used for analyzing risks of the power distribution network according to the current power distribution network model and the running mode; the risk solution module is used for analyzing solution strategies for the power distribution network risks to obtain a power distribution network risk solution strategy; the analysis result display module is used for displaying a power distribution network risk analysis result and a power distribution network risk solution strategy analysis result. The power grid model and the on-line power grid running mode are synchronized in real time from the power distribution network SCADA system, and real-time performance of risk analysis is guaranteed; rich risk warning display means are provided, and users are assisted to quickly position a risky area; the risks of the power distribution network are analyzed from the perspective of the power grid running mode, advance discovering and timely processing are achieved, and power supply reliability of the power distribution network is improved.

Description

technical field [0001] The invention relates to a distribution network operation risk early warning system based on real-time operation state evaluation, and belongs to the technical field of distribution network. Background technique [0002] The distribution network is an important part of the power system, and its safety and reliability will directly affect the development of the national economy and people's living standards. According to incomplete statistics, 80% of power outages in our country are caused by distribution network faults. Therefore, early warning of distribution network operation risk has very important practical significance. [0003] The existing distribution network early warning system is mainly analyzed from two aspects: equipment risk and environmental risk. Equipment risk mainly refers to the risks encountered during the operation of distribution network lines and their equipment, including quality risks caused by product quality and operational...

AI Technical Summary

Problems solved by technology

The impact of the operation mode on the distribution network is ignored. For example, the long-term heavy-load operation of the line will accelerate the aging of the distribution network equipment, and even heat and burn; the ring network operation will cause unnecessary loop closing current on the line, etc.
