摘要：

A nonlinear design technique, DFL (direct feedback linearizing), is used to deduce the control law for the TCSC (thyristor controlled series compensator) and SVC (static VAR compensator). The coordination between the two pieces of equipment is also designed in the paper with the SVC treated as the supplement of the TCSC. When operation of the TCSC is constrained by the inherent limitation of equipment, the adjustable SVC can supply the auxiliary support to improve the overall performance. In order to adapt to the changes of the operating mode and active power of generators, a neural network (NN) is applied to determine the control parameters of the equipment. Analysis and simulation of a case study have proved the effectiveness of the nonlinear control strategy. (C) 1999 Elsevier Science Ltd. All rights reserved.
