【摘要】 介绍一种基于 DSP(数字信号处理器)的新型智能式无功补偿控制器。详细给出了控制器的控制策略和系统结构。该控制器采用 DSP 和单片机双 CPU 方案,控制晶闸管投切电容器。其结构紧凑、控制方法灵活,能根据负荷的变化情况,选择最佳方式进行动态无功补偿,不会产生无功倒送和投切振荡,通用性强,智能化程度高。更多还原

【Abstract】 A new kind of intellectualized reactive-load compensation controller based on DSP is presented.The control strategy and system structure are discussed in detail.A double CPU project composed of DSP and SCM is introduced to control thyristors to switch capacitors.It can choose optimal mode according to varying load without reactive-power resersing and oscillating.The controller with tight structure and flexible control methods,is more universal and intellectualized.更多还原
