近年来，浦东电网的负荷水平逐年提高。在夏季用电高峰期，配电线路的允许容量是配电网的瓶颈。为了提高现有重负荷配电线路的供电能力和线路设备资产的利用效率，可对配电线路的绝缘导线和裸线采用动态线路额定值系统。该系统设计并应用于浦东电网35kV、10kV架空配电线路。通过去年夏季用电高峰的运行，该系统可使配电线路的容量增加20%左右。可以为调度检查人员在用电高峰时段采取瞬时安全措施提供科学参考，在某些情况下减少甚至消除不必要的减载操作。
In recent years, the load level of Pudong Power Grid is increasing year by year. In the summer peak period, the allowable capacity of the distribution line is the bottleneck of the power distribution network. In order to improve the power supply capacity of the existing heavy load distribution lines and the utilization efficiency of the line equipment assets, a dynamic line rating system, this can be applied to the insulated conductors and bare wires of the distribution lines. The system is designed and applied to the 35kV and 10kV overhead distribution lines in the Pudong power grid. Through the operation of last year's summer peak, the system can increase the capacity of the distribution line by about 20%. It can provide a scientific reference for the dispatching and inspection personnel to take the instantaneous safety measures at the peak time of the power consumption, and reduce and even eliminate the unnecessary load reduction operation in some cases.
