| 摘 要： | 阐述了静止同步补偿器(STATCOM)的基本原理和补偿策略。应用模糊控制理论Takagi-Sugeno型模糊推理模型,设计了STATCOM非线性变增益PI控制器,其控制增益能够根据电力系统当前状态依据规则产生大范围调整,在较大的系统工作空间内均可有效提高电力系统电压调节能力和暂态稳定性能。针对含STAT-COM的单机-无穷大(SMIB)系统进行的电力系统暂态仿真,结果表明:该控制器性能优于常规PI控制器。

| Abstract: | The principle and control strategy of a static synchronous compensator(STATCOM)are analyzed.A nonlinear variable gain fuzzy PI controller for STATCOM was designed via Takagi-Sugeno(T-S)type fuzzy model.The characteristics of the gain variation were parameterized and governed by the rule proportionality.The controller provides suitable voltage control and transient stability enhancement over a wide rang of operating conditions of power system.The transient simulation results on a single-machine infinite-bus system(SMIB)including STATCOM show that the performance of the proposed controller is better than conventional PI controllers. |
