Abstract

This paper reports on a load controller for a standalone wind power plant with storage. The controller incorporates a maximum power point tracking (MPPT) algorithm for always capturing maximum energy from wind flow. The load is modelled as a three-phase resistor and is interfaced with the variable speed wind turbine and permanent magnet synchronous generator (PMSG) through a diode bridge rectifier, DC-DC converters, and a three-phase voltage source inverter. Maximum power point tracking is implemented by varying the duty cycle of a boost converter with the changes in the DC-link power and voltage. The energy storage system comprises a lead-acid battery bank that stores excess energy and supplies the load when wind generation cannot sufficiently meet the load demand. The three-phase voltage source inverter converts DC voltage to AC and employs vector control to sustain a constant output voltage across the load. Modeling and simulation are performed in MATLAB/Simulink for varying wind speeds and loading scenarios. The simulation results demonstrated that the controller performs well under these conditions.

带储能的独立式变速风能转换系统负荷控制器

本文报道了一种用于独立式带储能风力发电厂的负荷控制器。该控制器采用了最大功率点跟踪(MPPT)算法，以便始终从气流中捕获最大能量。负载建模为三相电阻，并通过二极管桥式整流器、DC-DC转换器和三相电压源逆变器与变速风力涡轮机和永磁同步发电机(PMSG)连接。最大功率点跟踪是通过随直流链路功率和电压的变化改变升压变换器的占空比来实现的。储能系统包括铅酸蓄电池组，用于存储多余能量，并在风力发电不能充分满足负载需求时提供负载。三相电压源逆变器将直流电压转换为交流电压，并采用矢量控制来维持整个负载的恒定输出电压。在MATLAB/Simulink中对不同的风速和加载场景进行了建模和仿真。仿真结果表明，该控制器在这些条件下具有良好的性能。
