Application of Wi-Fi Module in Power Compensation Cabinet

With the proposal made by the State Grid Corporation of China on the overall development plan of the smart grid, the power patrol will gradually become automated and intelligent, and it will eventually be unattended.

The power inspection includes the inspection of the power grid circuit and the inspection of key power supply equipment. The staff members can inspect the operation status of the equipment through inspection, and discover equipment defects and hidden dangers in a timely manner. The commonly used method for inspection of power equipment is to use manual opening. The cabinet directly reads and reads device data. The operation mode is complex and time-consuming, and there is a certain degree of danger. With the continuous development of electric power intelligence, the data exchange of many power devices has become wireless, and the power inspection has also changed. It is more and more convenient and fast, in which patrol power equipment through Wi-Fi is a common method.

Case details

With the proposal made by the State Grid Corporation of China on the overall development goals and planning of the smart grid, the traditional substation manual inspection operation mode has not been able to meet the requirements of the development of the situation. Integration automation and intelligentization are gradually being unattended as the main development direction in the future. In the routine maintenance operations of switch cabinets and compensation cabinets in substations, non-contact patrol inspections are used instead of manual direct operations to reduce the number of operations performed by personnel and reduce safety risks.

Application of WiFiCOM-10T in Power Compensation Cabinet

The inspection of the power compensation device generally requires manual opening of the cabinet for data viewing, adjustment, and other operations. The work is cumbersome and dangerous. This project utilizes the WiFiCOM-10T serial port to the Wi-Fi module to use the original device based on the original The RS-485/232 communication interface quickly upgrades the product and converts the serial port data into Wi-Fi signals. The inspection personnel can conduct equipment inspection through the mobile phone or iPad, and realize functions such as remote control, telemetry, and remote signaling.

In addition, WiFiCOM series products have a strong signal coverage performance, even in the case of external antenna equipment inconvenience, fully enclosed metal cabinet can still be stable transmission, widely recognized in many power projects.
