Actually I incorporate it into a system which consists of a induction generator, diesel generator and loads.< > Are the diesel generator and the rest connected after the fault or is the diesel gen running unloaded in parallel? Is the diesel generator a synchronous one or another asynchronous machine? if synchronous - does it incorpoarte an exciation system or is the excitation constant? Does the diesel engine have a speed/load controller or is the machine input (speed/power or torque) constant? What type of loads you have-inductive and/or capacitive? > > > But my diesel generator gives weird response.< > Do you start the model in steady state (have you carried out a load flow analysis) or do you just start the simulation? Does the weird system behaviour occur immediately after starting the simulation or after some time (synchronising the diesel engine, after simulating a short circuit or whatever your model does)? What signals are weird - oscillating voltages, oscillating active power, oscillating reactive power? > > Regards > Frank |
