Abstract

A joint VAr (volt-ampere reactive) controller is described which was designed for use at Manitoba Hydro´s Dorsey converter station. The controller was tested in closed-loop mode using a fully digital real-time simulator. By performing a broad range of simulated system disturbances the controller´s operation could be verified before its installation. The testing proved useful in verifying the controller concept, confirmed proper operation of the controller software, and allowed parameter sensitivity analysis, which could not have been carried out during site tests at the inverter station. Comparison of simulation results and the results of some preliminary field tests is also documented
