基于单机无穷大母线等值和轨迹灵敏度的暂态稳定最优励磁控制
Optimal Transient Stability Excitation Control Based on OMIB Equivalents and Trajectory Sensitivities
摘要
Abstract
In order to fial-ther decrease power system transient stability control costs, system fast dynamic device set points optimal control was proposed in this paper to guarantee system transient stability under contingency. An optimal transient stability excitation control (OTSEC) quadratic model based on a one-machine-infinite-bus (OMIB) equivalent and a trajectory sensitivity method was proposed in this paper to maintain power system stability, which was used to determine the generator voltage regulator reference set points. An OMIB equivalent was used to introduce a strict transient stability criterion into the OTSEC model, and a trajectory sensitivity method and a stability margin index were proposed here to enhance computational efficiency. Since the stability margin index was adopted, the need for searching critical stable trajectories for unstable faults was avoided and hence simulation time was greatly saved. The feasibility and effectiveness of the proposed method are demonstrated and verified on the 10-machine and 39-bus New England system and a provincial 138-machine and 692-bus system.关键词
