一种变电站用智能化检修调试平台的研制

Development of Intelligent Maintenance and Debugging Platform for Substation

为解决变电站内仪器设备搬运困难、带电区域与检修区域共存、常规测试电源不满足要求的问题,设计了动态平衡机构及控制方法、带电设备感知安全隔离方案以及自备可调柔性试验电源。研制了一款适用于变电站内工作的多功能检修调试工作平台,实现智能供电、带电区域隔离等功能。在江苏电网多座220 kV及以上变电站的实际应用验证了该平台的有效性与安全性。

It is hard to handle the instruments and equipment,in the substation and the operating area and overhaul area exist together in it,so the conventional test power supply is used to hardly satisfy the test requirements.Dynamic balance structure with correspanding control method,isolating scheme based on live equipment perception and self-provided adjustable flexible test power supply is designed in this paper.A multi-function maintenance and debugging platform with features is developed,which is used to implement,smart power supply,electric area isolation and so on.The efficiency,and safety of the platform are verified in the practice test at the 220 kV and over substations of Jiangsu power grid.
