摘要
以研究电网暂态稳定性为目的,应用概率性方法进行分析计算,并以此来评估电网的暂态稳定情况,主要考虑了两个因素:电网故障的随机性和电力负荷变化的随机性,并在此基础上提出了用于评估电网暂态稳定性的概率指标,同时利用VC++灵活便捷的控制语言以及BPA(Bonneville Power Administration)软件计算暂态稳定的快速准确性,研究了适用于大型复杂电网暂态稳定性概率评估的接口技术,通过该接口技术希望能够大大地减少计算分析的时间。最后,通过对IEEE-9节点网络以及我国华东某地区2010年220kV规划电网进行分析计算,验证了所提方法的有效性同时证明了速度可以得到大大地减少。
To study the transient stability of power system, the probabilistic method is employed for analysis and calculation, and is used to estimate the transient stability of power system. Two uncertain factors of power system are considered including fault occurrence and load demand. The probability indexes are suggested. A new interface technique is developed to analyze the probabilistic transient stability of complex power system using BPA （Bonneville Power Admin istration） and VC ＋ ＋. The analysis and calculation for IE EE-9-bus network and 220kV planning network in 2010 of some city in East China, prove that this interface is feasible and efficient.
