同步发电机励磁与STATCOM非线性协调控制

摘要

Nonlinear coordinated control is presented for synchronous generator excitation and Static Synchronous Compensator (STATCOM) in this paper. Considering the coordinated control problem of synchronous generator excitation and STATCOM, multi-objective equations are built to include system variables interested by practical operation. When Nonlinear Control method with Objective Holographic Feedbacks (NCOHF) is applied to deal with above coordinated control, a nonlinear control method, called Nonlinear Coordinated Control with Objective Holographic Feedbacks (NCCOHF), is proposed. In this condition, satisfactory dynamic and static-state performances of terminal voltage, active power and angular speed are achieved except for the voltage at the STATCOM connection point. This is because these variables are punished during the course of nonlinear feedback. Finally, simulation model is built to examine the effectiveness of the proposed method.%提出同步发电机励磁与静止同步补偿器（Static Synchronous Compensator，STATCOM）非线性协调控制方案。在研究同步发电机励磁与静止同步补偿器协调控制问题的基础上，以系统重要物理量建立多目标控制方程，并运用目标全息反馈法进行非线性协调控制设计。所提出的非线性控制方案充分考虑了同步发电机端电压、有功功率和角速度以及STATCOM接入点电压，并确保它们在非线性反馈中得到惩罚与控制，从而具有良好的动、静态性能。最后，建立系统仿真模型，进一步验证所提出方法的有效性。
