Hunan Electric Power: Substation New Technology to Drive Birds to Ensure EHV Power Grid Stable Operation

Recently, Changsha 500 kilovolt Ai Jia Chong substation, Hunan Electric Power Company maintenance and repair company is on the new installation of new bird equipment tour. Hunan actively promote the use of new technology to drive bird equipment, to ensure the safe and stable operation of EHV power grid.

Hunan Substation

Time Spring is the season for the breeding of small animals. Birds begin large-scale nesting. Installation of high-performance bird-fighting devices in the 500 kV substation of the UHV grid in the mountainous area will eliminate the need for birds to nest on substation equipment Equipment, power grid security risks have an important role. According to reports, in the past, the installation of anti-bird devices in substations had to provide power for the bird-repellent device alone. Because of the connection between the power supply and the substation's AC control power supply, there was a certain risk to the reliable power supply of the grid equipment. In addition, The surrounding impact is not conducive to large-scale use.

The operation of the new type of bird driving device, the use of solar panels plus storage batteries in the form of power supply around the clock, without taking the station AC power supply; Bird using a relatively small noise ultrasonic bird drive, the effective range of 20 meters, through Reasonable distribution in the station area ensures the full coverage of the main equipment in the station. By intermittently transmitting the ultrasonic wave, birds are prevented from being adapted to the long-term fixed emission interference sound waves. In addition, the installation of the new bird-fighting device is also more convenient. The installation of a device takes just over 10 minutes and the installation time of older bird-fighting devices for at least an hour greatly improves the efficiency.

The installation of the new anti-bird device selection in all directions surrounded by mountains, affected by the birds more affected 500 kilovolt Aijia Chong substation, bird protection net effect more pronounced. The company plans to further promote the use of the device at a 500 kV substation under its jurisdiction.
