一种基于BPA数据的静态安全最优校正分析方法

摘要

Static security correction is an important measure to ensure the safe and stable operation of power system and plays vital guiding role for drawing-up of operation modes and planning and construction of the system. This paper presents a preventive static security correction method which is based on BPA data format,combining the modern Interior Point Theory and Compensation Method to meet the requirements of the N-1 security rule. The results of testing it in the real power grid show that this method can filter out N-1 faults quickly and accurately and give the reasonable operation mode. Consequently,it can eliminate possible contingences which do not meet the N-1 rules and improve the system’s security and stability.%电力系统静态安全分析是保证系统安全稳定运行的重要措施，对电力系统运行方式的制定以及系统的规划建设具有重要的指导作用。提出了一种基于BPA格式数据，采用现代内点理论并结合补偿法进行校正计算，满足N-1安全准则的静态安全最优预防校正控制方法。通过在实际电网中进行测试表明，该方法可以快速准确地筛选出系统的N-1故障，给出合理的系统运行方式，消除不满足N-1安全准则的预想事故，提高电力系统的静态安全稳定性。
