常見問題及解決方法:
Common problem and solution:
由于一些可能出現的接線、設置、硬件故障等,會造成整個電容補償系統不能正常工作,現將較多出現的故障及檢查排除方法介紹如下:
The entire capacitance compensation system can not operate normally because of some possible fault in cable connection, configuration and hardware. See below fault which happed frequently and its exclusion method:
1.       控制器測量電流顯示值錯誤或為000
檢查參數設置菜單“電流變比”設置項,其設置的值必須與主進線電流互感器的比值相同,如主進線取樣電流互感器變比為800/5,控制器“電流變比”設置值應為160;當電流顯示0000A時,表示沒有電流信號,應檢查電流互感器與控制器電流連接端子線路有開路或沒有負載兩種情況。
1.    Value of the controller meter current displays wrongly or is 000
Check “current conversion ratio” setting option in parameter setting menu, setting value should be same as the conversion ration of the main incoming current transformer. In case the conversion ration of the main incoming sampling current transformer is 800/5, the “current conversion ratio” setting value of the controller should be 160; When it displays that the value of the current 0000A, it means no current signal, please check open circuit or no load conditions of the current transformer and the current connection terminal circuit of the controller.
2.       控制器報警指示燈亮
當電壓、諧波測量顯示值超出設定的上、下限保護值的范圍時,控制器報警指示燈亮。控制器將按“5s”間隔時間切除已投入電容器,應適當調整上、下限保護值。
2.    Alarm indication lamp of controller is lighted.
When display value of voltage is out of the scope of upper and lower limit protection value, alarm indication lamp of controller is lighted. Controller is switched off at “5s” time interval and the capacitor is switched on, the upper and lower limitation protection value should be suitably adjusted.
3.       功率因數顯示錯誤
應檢查控制器的測量電流和測量電壓的對應關系,測量電流與測量電壓應為同相。
3.    Display of power factor is wrong.
Check the corresponding relationship between metering current and metering voltage of controller, the metering current and the metering voltage should be in-phase.
4.       補償效果不好
應檢查控制器參數設置項,與補償精度相關參數有“目標cosΦ”,“門限”、“電容容值”三個參數,可提高“目標cosΦ”值,減小“門限”設定值,推薦設置為目標cosΦ:1.00,門限1.0,每組電容容值設定與實際電容容值相同即可。由于一些設計電容容量分配級差較大,推薦使用電容編碼方式,調整電容器容量,將會達到理想補償效果。
4.    Bad compensation effect
Check parameter setting option of controller. The parameters which are related to the compensation precision are target cosΦ, threshold and capacitance three parameters.  The target cosΦ can be improved and the setting value of threshold is reduced, it is recommended that target  cosΦ is 1.00 and threshold is 1.0, the capacitance of each group of capacitors should be same as that of the actual capacitor. Because the capacity distribution stage difference of some design capacitors are much, it is recommended to apply capacitor coding method and the capacity of the capacitor is adjusted, it would reach the ideal compensation effect.
5.       不便判斷問題出在外接線路時,可換一臺控制器,如出現相同的故障現象,請您務必按以上提示檢查外接線路。
5.   In case it is difficult to judge that problem occurs on the outer connection line, please replace with another controller. If same fault phenomenon appears, you should check the outer connection line following above mentioned procedure.
