Application of Wi-Fi module in power compensation cabinet

With the State Grid Corporation of China proposing the overall development plan for smart grids, power inspections will gradually move towards automation and intelligence, and eventually achieve unmanned operation.

Power inspection work includes inspection of power grid lines and inspection of key power supply equipment. Through inspection, staff can understand the operating status of equipment and promptly discover equipment defects and safety hazards. The common way to inspect power equipment is to manually open the cabinet to directly view and read equipment data. This operation is relatively complicated and time-consuming, and there is a certain degree of danger. With the continuous development of power intelligence, the data interaction of many power equipment has been wireless, and power inspection has become more and more convenient and quick. Among them, interactive inspection of power equipment through Wi-Fi is a common method.

Case details

With the State Grid Corporation's overall development goals and plans for smart grids, the traditional manual inspection and operation mode of substations can no longer meet the requirements of the development of the situation. Integrated automation and intelligence are gradually moving towards unmanned operation, which is the main development direction in the future. In the daily maintenance operations of substation switch cabinets and compensation cabinets, non-contact inspection is used instead of direct manual operation to reduce the number of operations by operators and reduce safety risks.

Application of WiFiCOM-10T in power compensation cabinet

Inspection of power compensation devices generally requires manual opening of cabinets to view and adjust data, which is tedious and dangerous. This project uses the WiFiCOM-10T serial port to Wi-Fi module to quickly upgrade products based on traditional devices using the original RS-485/232 communication interface, converting serial port data into Wi-Fi signals. Inspection personnel can inspect equipment through mobile phones or iPads, and realize remote control, telemetry, and telesignaling functions.

In addition, the WiFiCOM series products have strong signal coverage performance. Even if the device antenna is not convenient to be externally installed, stable transmission can still be achieved in a fully enclosed metal cabinet, and are widely recognized in many power projects.
