【 摘 要 】

This paper presents the reactive power compensation of an isolated wind-diesel hybrid power system. The wind energy conversion system is using a permanent magnet induction generator (PMIG) and synchronous generator (SG) is used with the diesel engine set. The PMIG requires less reactive power compared to an induction generator for its operation and this demand is continuously changing by the variation of load and wind power. Most of the loads are inductive in nature and to capture the dynamic performance of a system, dynamic load modelling is done. The load considered in this case is an induction motor. The synchronous generator used by the diesel generating system partially supplies the reactive power needed by the system. The mismatch between generation and consumption of reactive power causes voltage fluctuations at generator terminals which reduces the stability and quality of the supply. To manage the mismatch a variable source of reactive power such as STATCOM is used. Reactive power flow balance equations are used for the mathematical modelling of the system. The MATLAB/SIMULINK environment is used for simulation.
