Analysis of P.I.D. Governors in Multimachine System

The effect of derivative gain and other governor parameters on the stability of a single machine supplying an isolated load is investigated. The effect of derivative gain and other parameters of the governors in a two plant system are investigated. The plants have different types of governors and are feeding an HVDC system. State space method is used for analysis and results are compared with detailed nonlinear model CSMP simulations.
