Analysis of Synchronous Generator Characteristics of Grid-Connected Voltage Controlled Inverter
摘要
Abstract
Aiming at better interfacing renewable energy with power grid, characteristics of synchronous generator for grid-connected voltage-controlled inverter are studied. In this paper, a voltage-controlled LCL type inverter with axes is researched. Firstly, on basis of a built mathematical model, with theoretical analysis, the frequency modulation axis in frequency control unit simulates prime mover power input, inertia link simulates generator rotor inertia and damping characteristics; voltage modulation axis simulates equivalent internal potential amplitude of the synchronous generator, so that it has basic function of synchronous motor. Secondly, active and reactive power regulation scheme of the axes-control inverter are studied. Influence of operating point change on active power tracking is analyzed quantitatively. An active power control strategy based on proportional coefficient adaptive adjustment is proposed, effectively solving accuracy problem of active control. Finally, validity of the theoretical analysis and the adaptive control scheme is verified by the simulation results.关键词
