To the requirement of smart fault decision-making, by using the discrete event system structure, the problem analysis system of fault diagnosis in distribution grid is built, analyzing the basic principles , demonstrating the diagnosability and uncertainty in the problem of fault diagnosis, meanwhile putting forward the method of process matching based on the timing sequence and protection differential...
The intermittent nature and immature forecasting technology of wind power make difficult to consider wind power generation into the day-ahead generation scheduling, and bring out a considerable challenge to load regulation capability for the regional grid. The paper theoretically analyzes the power system load regulating capacity according to units' security and system operation constraints. According...
In this paper, design and development of power plant relay setting calculation expert system is researched. It highlighted the intelligence and scalability of the software. It has good adaptability, and could significantly reduces a large number of duplication effort of engineering and technical personnels.
Protection setting calculation and data management for main equipment in power plant is an important technical foundation for the work. Relay devices of main equipment protection have no uniform criterion and the style of each corporation is distinctive. The setting is time-consuming and laborious with heavy workload. Aiming at the current practical situation, this paper describes the design scheme,...
