配电网电压等级是指配电网（配网）的额定电压级别系列。配网指的是电力系统中输配电里面的配电，就是电能被分配到各个用户处的这一级。配网又有高压配网和低压配网之分。额定电压是电力系统及电力设备规定的正常电压，即与电力系统及电力设备某些运行特性有关的标称电压。电力系统各点的实际运行电压允许在一定程度上偏离其额定电压，在这一允许偏离范围内，各种电力设备及电力系统本身仍然能正常运行。
提高配电网电压等级是提升城市电网供电能力的有效途径。
To lift the voltage level of distribution network is an effective method to enlarge the power supply capacity of the urban network.
城市配电网因为其电压等级较低，为了提高系统供电的可靠性，曾广泛采用中性点不接地系统方式。
In distributions, because of its low-level voltage, its neutral point used to disconnect to the ground in order to improve its reliability.
研究是基于高压配电网的，但其所用的算法和方法也适用于其他电压等级的配电网络。
Though the research described is based on the HV distribution network, the algorithms and techniques described here could also be adopted by other voltage level distribution network.
