Research on the inverter circuit of power generation system

Inverter of power generation system makes the residual pressure of natural gas pipeline into alternating current or using as a power source. It provides clean energy for equipment maintenance and staff who work in the outdoors. With the development of power electronic technology, the distributed generation system attracts more and more attention in the countries around the world, inverter of power generation system based on residual pressure of natural gas pipeline has been used in many countries and got good results. This paper introduces the overall structure of the inverter system and establishes the mathematical model of inverter based on space vector pulse width modulation (SVPWM). The method of control is presented which is combination of voltage feed forward controller and current proportional-integral controller. Finally, the corresponding partial design of the 1.5 KW inverter circuit is given. Proved by experiments, the inverter of SVPWM-based control will produce good three-phase power to grid or using an independent power supply.
