Study on Simulation and Protection of Induction Motor in the Independent Power System
|Title||Study on Simulation and Protection of Induction Motor in the Independent Power System|
With the shortage of energy around the world, it is an inevitable trend in china’s future energy development that great efforts will be made to exploit offshore oil and gas resources. As the main power drive equipment, induction motor plays an important role in the offshore oil platform system. So it is meaningful to study on simulation and protection of induction motor on the offshore oil platform independent power system. Firstly, the paper studies the mathematical model of induction motor, proposes a model of induction motor with the consideration of iron loss and magnetic saturation. Then the paper studies the simulation of common fault of induction motor depend on the independent power system simulation model which is established in MATLAB. Secondly, base on the study on fault simulation and protection of induction motor, the paper proposes a scheme of comprehensive protection configuration of induction motor on the offshore oil platform independent power system. Finally, with the study on simulation of interphase short circuit fault of induction motor on independent power system, the paper proposes a scheme of time overcurrent protection which has power directional element.
