利用直接反馈线性化理论,将静止无功补偿非线性控制问题转化成伪线性控制问题,且考虑实际系统不确定性因数的影响,设计出了静止无功补偿状态反馈鲁棒控制规律。并对单机无穷大系统进行了数字仿真,仿真结果验证了该控制算法的有效性,可以更有效的改善电力系统动态稳定性。
Using the theory of direct feedback linearization, the problem of nonlinear control of STATCOM is transformed into a pseudo-linear control problem. Considering the influence of the uncertainties of the actual system, a robust control law of STATCOM is designed. The numerical simulation of the single machine infinite system is carried out. The simulation results verify the effectiveness of the control algorithm and can effectively improve the dynamic stability of the power system.
