Pumped storage unit fault analysis system and pumped storage unit fault analysis method

Abstract

The invention relates to a pumped storage unit fault analysis system and a pumped storage unit fault analysis method. A monitoring system principal computer acquires and processes real-time data of a pumped storage unit, and provides a list of information of a fault event record and a curve record. A background processing module calls a list of information of the monitoring system principal computer, queries and optimizes data, and interacts with an algorithm module on acquired characteristic information. The algorithm module extracts corresponding characteristic rules, analyzes and judges the start-stop process of the pumped storage unit, and raises the alarm if there is a fault or abnormality. Meanwhile, the algorithm module calculates related information at the end of the process, and updates the revised values of the corresponding rules. A knowledge base management module provides a management interface, and writes the characteristic rules of the start-stop process of the pumped storage unit. Through the system, real-time process running information can be obtained, process abnormality can be reflected, and a double adjustment function is achieved.

Description

technical field [0001] The invention relates to the technical field of power system monitoring and analysis, in particular to a fault analysis platform for the start-stop process of an energy storage unit based on a knowledge base. Background technique [0002] At present, the construction of pumped storage power stations in my country has entered a period of rapid development. Pumped storage units undertake various tasks in the power system such as peak regulation, frequency regulation, phase regulation, emergency backup and absorbing excess electric energy. The pumped storage unit is a reversible unit with various and complex working conditions and many cooperative equipment. The status performance of each equipment directly reflects the operating performance of the unit. In order to ensure the safe operation of the power grid and energy storage units, give full play to the peak regulation and frequency modulation capabilities of energy storage units, and improve the cont...
