Experiment Study on the Control Method of Motor-Generator Pair System
The environmental problem is a major practical problem that China and the world are faced with. It is a trend for the future power grid to be dominated by the increasing penetration of renewable energy. However, the high penetration power system may face many new problems, including reduced inertia...

The environmental problem is a major practical problem that China and the world are faced with. It is a trend for the future power grid to be dominated by the increasing penetration of renewable energy. However, the high penetration power system may face many new problems, including reduced inertia of the power system, the stability of the frequency stability, and the weak grid characteristics of the output system may limit the delivery capacity of renewable energy base. The motor-generator pair (MGP) system can deal with these problems efficiently, but the current MGP system control method is still flawed. In this paper, the mathematical model of the MGP system is analyzed. The characteristics of the source-grid difference control method is analyzed by simulation and experiment. In the experiment, the shortcoming of existing control method that the control system is sensitive to the power grid frequency change is found. The optimized control method based on power feedback is proposed. The feasibility of the power feedback control method is proved by the experimental and simulation. The result shows that the source-grid phase difference method based on power feedback can make the MGP system follow the power reference value to transmit active power stably and reduce the frequency sensitivity of the MGP system. |
