Inverse-system method
Simulation Study of Affecting Dynamic Fault Recovery Performance of HVDC System with STATCOM
The transient mathematical model for the STATCOM in d-q synchronous reference frame is developed. It applies the inverse system method based on nonlinear feedback linearization theory. An inverse system model of STATCOM is deduced and a pseudo linear system is constructed. Then, by synthesizing the pseudo linear system, a sliding mode variable structure controller is [...]
Research on the Coordinated Control of Unit Plant Based on Neural Network Inverse System
As the main control system of unit plant, an effective thermal power plant unit coordinated control system is the key to raise the level of thermal automation and the economic efficiency of power plant. For boiler-turbine unit, a complex object with the characteristic of multivariable, nonlinear, large delay, and uncertainty, the traditional coordinated control system [...]
Study on Excitation Source Control Policy of Variable Speed Constant Frequency Double Fed Wind Power Generation System
Nowadays the problems of energy lack and environment pollution are more and more serious, the utilization of renewable energy is popular all over the world. Wind power generation develop rapidly because of its cleanliness and free pollution. Variable speed constant frequency (VSCF) double fed wind power generation is the research hotspot in wind power generation [...]
Active Power Smoothing Control of Wind Generation System
Wind power is a clean and renewable energy. The fluctuations of wind power often occur as the stochastic feature of wind speed. With the increase of the wind power capacity in power grid, the change of power and frequency in power system will exceed the limit range when the fluctuation of the wind speed is [...]
