摘要
随着供电可靠性要求不断提高,重要会议和活动现场保电均需要提前接入低压发电车,但低压发电车接入时需市电短时停电,难以实现带电并网和"零停电"保电,越来越难以满足特殊保电场所全天候不停电的要求.文章对现有的低压发电车进行简单改造,解决了带电接入、带电并网、带电退网等技术难点,能实现大部分情况下的"零停电"保电需求.
Abstract
With the increasing requirement of high power supply reliability,the low-voltage power supply vehicle needs to be prepared for power supply of important meetings and activities in advance.However,when a low-voltage power supply vehicle is connected to the grid,it is difficult to achieve hot-line connection and"no power failure",and it is increasingly difficult to meet the requirement of no power failure in special sites.This design is based on the necessary reform of the existing low-voltage power supply vehicle,which can solve some technical difficulties such as hot-line connection,positive&negative synchronism,and can meet the requirement of"no power failure"in most cases.
