【Abstract】 New energy power generation and its grid-connected theory and technology are currently an important content of electrical engineering undergraduate level and also are teaching and research hotspot in electrical engineering disciplines. It involves the theoretical knowledge of multiple courses. An emulated new energy power generation and grid-connected control comprehensive experimental system is developed with permanent magnet motor platform, converter control unit, measurement and display unit, etc. Also, the phase-locked loop, grid-connected control dead zone compensation, grid-connected active/reactive power regulation and new energy grid-connected power generation experimental teaching content are designed. The developed experiments will help students understand and master the characteristics of new energy power generation, the principle of grid-connected control and its implementation technology. Moreover, they can cultivate the engineering practice ability.更多还原
