本文针对柴油发电机组并联运行时易产生的“游车”情况,提出了一种新型频率控制方案。采用DSP虚有差法分配负荷,在优化系统频率输出的同时,也能够快速稳定柴油机因供油不均引起的输出功率波动。经Matlab软件仿真,校验了这种控制手段的有效性。
This paper proposed a new frequency control scheme, for diesel generators parallel operation easy causing "hunting" situation. By using DSP virtual discriminating method to distribute load, meanwhile optimize the system frequency output, can rapidly stable power supply fluctuations caused by uneven oil supplied. The Matlab software simulation, verify the validity of the control method.
