摘要
提出了一种利用故障过滤技术的可利用传输能力快速计算方法。利用迭代线性交流潮流法对热稳定约束和电压幅值约束条件进行N?1故障过滤,利用线性灵敏度法对电压稳定约束条件进行N?1故障过滤,得到最严重故障集;利用原-对偶内点法只针对若干最严重故障计算系统可利用传输能力。该算法提高了计算效率,同时保证了计算精度。算例仿真结果验证了所提算法的准确性和快速收敛性。
A fast computation method for available transmission capability is proposed by use of contingency screening technique. Using iteration linear AC power flow method, the N-1 contingency screening for thermal stability constraint and voltage amplitude constraint is performed; using linear sensitivity method the he N-1 contingency screening for voltage stability constraint is performed to obtain most severe fault set; using primal-dual interior point method the available transmission capability of power system under several most severe faults is calculated. It is verified by simulation results that the proposed method can improve calculation efficiency and ensure computation accuracy.
