工作模式的特點,任何時刻控制器只能工作在1 種工作模式下
The characteristics of the working mode, the controller can only work in one working mode at any time
功率因數控制模式的特點:本控制器在出廠前已將工作模式調整在功率因數控制模式下,所有參數已按合理的方式預置,用戶只要接線正確就能正常工作,無須任何操作。
無功功率控制模式的特點:能精確的控制電容器組的投切無投切震蕩,適合所有工作環境特別是負載輕電容容量大的場合。
Features of power factor control mode: The controller has been adjusted to work in power factor control mode before leaving the factory, all parameters have been preset in the most reasonable way, the user can work normally without any operation as long as the wiring is correct.
Features of reactive power control mode: It can precisely control the capacitor bank without throwing oscillation, which is suitable for all working environment, especially for the occasion of light load and large capacitor capacity.
功率因數控制模式與無功功率控制模式的選擇
Selec tion of power factor control mode and r eactive power control mode
控制器工作模式的選擇是利用 參數的取值不同來區別的,如用戶將參數調節在(1-12) 內則表示控制器工作在功率因數模式下,數據的大小表示控制器輸出回路的多少,如用戶將參數調節在(50-5000) 則表示控制器工作在無功功率控制模式下,數據的大小表示用戶系統總電流互感器變比。
注:在無功功率控制模式下用戶在沒有使用控制器之前必須給控制器輸入實際電流互感器變比及所有電容器容量等參數。
The working mode of the controller is selected by using different values of parameters to distinguish, such as the user will adjust the parameters within (1-12) means that the controller works in the power factor mode, the size of the data indicates how much the controller output loop, such as the user will adjust the parameters in (50-5000) means that the controller works in the reactive power control mode, the size of the data indicates the user's total system current Transformer ratio.
Note: In the reactive power control mode, the user must input the actual current transformer ratio and all capacitor capacity parameters to the controller before using the controller.
