摘要
逆变电源是实现核反应堆反应性控制的重要设备,现有的逆变电源无法在供电电源波动和运行频率变化时使实际直流运行电流保持恒定。为了使实际直流运行电流恒定,本文研究了一种逆变电源直流反馈控制技术,以实际直流运行电流作为反馈量,采用比例-积分调节器进行反馈控制,使用空间矢量脉冲宽度调制(SVPWM)算法将给定运行频率和调节器输出调制成驱动逆变桥动作的脉冲宽度调制(PWM)信号。通过仿真结果证明了该方法的可行性,同时研制了反馈型逆变电源,并通过试验验证了该技术的有效性。
Inverter power is the important equipment to realize reactivity control of nuclear reactor.The existing inverter power can not keep the actual DC operating current constant when the power supply fluctuates and the operating frequency changes.In order to make the actual DC operating current constant,this paper studies a DC feedback control technology of inverter power,which takes the actual DC operating current as feedback,uses proportional-integral regulator for feedback control,and uses space vector pulse width modulation(SVPWM)algorithm to modulate the given operating frequency and regulator output into pulse width modulation(PWM)signals that drive the inverter bridge.The feasibility of this method is demonstrated by simulation,and a feedback inverter power is developed.The effectiveness of this technology is verified by experiments.
