摘要
针对30 kW微型燃气轮机发电系统存在运行不够稳定、功率分配不精确、抗负荷波动能力差的问题,在PSCAD中搭建了30 kW的微型燃气轮机发电系统的仿真模型,研究了恒功率控制和恒压恒频控制的特点。再结合恒功率控制和恒压恒频控制协调控制发电系统的运行,在并网和离网模式下解决了微型燃气轮机发电系统运行不够稳定的问题,并使负荷可以精确分配,提高了系统的抗负荷波动能力。
In allusion to problems such as unstable operation, inaccurate power distribution, poor ability of anti-load fluctua- tion, and so on of the generation system of 30 kW micro gas turbine, a simulation model for the generation system of 30 kW micro gas turbine is constructed in PSCAD and characteristics of active power reactive power（PQ） control and voltage fre- quency （VF） control are studied. PQ control and VF control is combined for coordinated control on operation of the genera- tion system, which can solve the problem of unstable operation of the generation system under grid-connection mode and off- grid mode as well as accurately distribute load and improve anti-load fluctuation ability of the system.
