基于NLPNN的电网可靠性评估模型

电力系统的根本任务是尽可能经济而可靠地将电力供给各种用户,安全、经济、可靠是对电力系统的根本要求。运用NLPNN模型,进行了电力系统故障状态的行为分析研究,提出了该问题的稳定性和收敛性定理,证明了求解负荷优化削减问题的可行性和收敛性。同时还提出了用NLPNN来对电力系统进行可靠性分析的新思路,且在电网可靠系计算分析模型方面取得了很大进展,为可靠性的计算提供了新的技术手段和理论基础。

NLPNN Model in Power Systems Reliability Evaluation

The purpose of a power system is to deliver the power the customers require in real time, on demand, within acceptable voltage and frequency limit, and in a reliable and economic manner. Using NLPNN (New Linear Programming Neural Network) model, the behavior analysis of power system under fault conditions is carried through. The stability and convergence theorems are set up to obtain the resolution for the problem of the load curtailment strategy. A new way is open up to evaluate the reliability of power systems and the great progress in calculation analysis model is achieved. The new calculation technique and theory foundation of reliability evaluation are supplied.
