AC electronic load and its application in power system simulation

A new method is introduced for simulating R, L, C load and power system steady state load based on SPWM power converter technology, and its control strategy is also proposed. Simulation results in this paper prove that such an AC-DC-AC converter can simulate the steady state and transient state performances of R, L, C load and the steady state performance of power system load very well. Besides, the simulation of motors and generators can be also accomplished by this principle and technology.
