1.电压偏移 不同的动力设备电压的概念不同。发电机电压是指发电机定子绕组产生的额定电压;变压器电压是指变压器高低压侧绕组的端电压;线路电压是指线路的运行电压等。电压反映电网无功电源出力与用户无功负荷是否平衡。我国规定用户受电端的电压允许偏移范围是: 1) 35kV及以上供电和对电压质量有特殊要求的用户为额定电压的±5％。 2) 10kV及以下高压供电和低压电
1. Voltage Offset Different concept of power equipment voltage is different. Generator voltage refers to the rated voltage generated by the stator winding of the generator. The transformer voltage refers to the terminal voltage of the high and low voltage side windings of the transformer. The line voltage refers to the operating voltage of the line. Voltage reflects the reactive power output of the grid and the user reactive load is balanced. China’s provisions of the user by the end of the voltage allowable offset range is: 1) 35kV and above power supply and the voltage quality of the special requirements of users rated voltage of ± 5%. 2) 10kV and below high voltage power supply and low voltage
