Why squirrel cage iduction generator gives minus power when running MATLABSIMULINK and ATP soft ware?

11 November 2016 1 3K Report

during simulation wind turbine by using software the power results in minus value.

the machine is used to be run as motor with absorbed power positive. Since you are dealing with generator, the power direction will be reversed and that's why it is recorded as negative power on measurement instrumentation of the digital library of SIMULINK. Even the torque-slip curve will be reversed in generation mode of induction machine.
