Research on Wireless Alarming System of Transformer Substation

How to find the faults and cope with the trouble in power system in the shortest time, becomes an intractable problem in electric power industry. With SCM technology, the authors put forward the two-level distributed structure composed of substations and transmission wires. Transmission line is provided with a plurality of alarm alarm extensions, information is transmitted to the alarm host through the wireless way. Substation can utilized management system to get alarm information by serial adapter of alarm host, at the same time the alarm information can be displayed on the computer screen.The system has been tested for many times in suburb of Nanyang city.The experiments showed that the systems operation is stable, achieve the expected design goal, which can also played a positive role in power management, power security at the same time.
