Compared with traditional nonlinear control method with single controlled variable, there are some novel characteristics of the nonlinear control method with multiple controlled variables. By choosing multiple controlled variables, the control performance of multiple variables could be coordinated, and the droop control could be realized. In the paper, the synchronous generator set is chosen as an...
Because the generator set model applicable to transient stability analysis is not suitable for the designing of nonlinear controller using only local measurements, it is modified into a new kind of model, or structural model of generator set, firstly. The structural model includes differential equations, interface equations and interface variable set. Based on the interface variable set, local measurements...
Three kinds of strict decentralized nonlinear controllers for synchronous generator set, including the excitation controller, governor controller, excitation and governor coordinated controller, are designed in the paper. The proposed nonlinear controllers are all based on complex model of generator set without ignoring the transient saliency of generator, and they all only feedback local measurements...
