Problems solved by technology

[0007] However, there are still the following problems in the inspection of smart substations in the existing technology: some of the existing monitoring and inspection methods only involve a background processing system, and do not consider the offline deployment of inspection terminals; although some comprehensively consider the background processing System and mobile terminal, but only suitable for monitoring the indoor environment of substations, manual inspection is required, or the terminal has no data processing and real-time display functions, and only plays the role of a scanner
Especially for the detection data flow that needs high-speed transmission in the smart substation system, there is no feasible real-time risk processing and analysis solution

Abstract

The invention aims to provide an intelligent substation real-time risk analysis system and an analysis method. Intelligent substation equipment monitoring data is analyzed based on a Spark big data processing platform. A data weight normalized processing algorithm and a risk time real-time judgment method are called to judge the risk point of an intelligent substation. Once that the intelligent substation is at risk is judged, risk analysis is made through a risk association model to locate risk inducing factors, and the result of risk analysis is synchronously transmitted to a handheld inspection instrument of an inspector in real time. Therefore, the real-time processing speed of intelligent substation system high-speed streaming data is improved, and real-time risk analysis is guaranteed.

Description

technical field [0001] The invention relates to the field of power systems, in particular to the field of real-time risk analysis of intelligent substations. Background technique [0002] Smart substation adopts advanced, reliable, integrated and environment-friendly intelligent equipment, with the basic requirements of digitalization of whole station information, networking of communication platform, and standardization of information sharing, and automatically completes basic functions such as information collection, measurement, control, protection, measurement and detection. , At the same time, a substation with advanced functions such as supporting automatic control of the power grid, intelligent regulation, online analysis and decision-making, and collaborative interaction. [0003] With the development of smart substations, the research on monitoring and inspection technology and risk assessment methods of smart substations has gradually increased. A common monitoring...
