摘要:
笔者设计了一种基于双DSP结构的三相四线制配电网静止同步补偿器(D-STATCOM),一个DSP负责采样、核心算法、SVPWM输出,另一个DSP负责外围监控与通讯,减小了处理器各自的负担,提高了实时响应速度。同时双DSP均具有保护功能,实现了保护功能的冗余设计,增加了设备运行的可靠性。通过dq变换,得到电网所需的无功电流,采用前馈解耦控制,实现了对无功电流的无稳态误差补偿;通过采样、三角波载波、PWM输出方式,实现了对零线电流的跟踪补偿。最后通过MATLAB仿真和50 kvar样机试验,得到了仿真和实验的数据及波形,验证了文中提出的基于双DSP结构的配电网静止同步补偿器设计的可行性,具有一定的实用价值。
Abstract:
A distribution static synchronous compensator(D-STATCOM) based on dual-DSP is designed, in which one DSP is responsible for sampling, core algorithm, and SVPWM output, and the other is responsible for monitoring and communication. This structure can reduce the burden on each processor and accelerate the real-time response speed. Both DSPs have a protective function, and the realization of the redundant design of protection function enhances the reliability of the equipment. Through dq transformation, the required reactive current of the grid is obtained, and the non-steady-state error compensation for reactive current is realized via feed-forward decoupling control. The neutral current compensation is realized by means of sampling, triangular wave carrier, and PWM output. In addition, simulation with MATLAB and experiment on a 50 kvar prototype are conducted to obtain the data and waveforms, which verify the feasibility and applicability of the D-STATCOM based on dual-DSP.
