Harbin Electric Group has developed the world's most advanced camera

The reporter learned from the Harbin Electric Machinery Co., Ltd. of Harbin Electric Power Co., Ltd. that the company successfully developed the world's most advanced new type of camera, and recently signed a contracting camera supply contract with the National Union of East Inner Mongolia Electric Power Co., Ltd. Ximeng converter station installed a regulating camera project At present, products are being stepped up. It is reported that Harbin Electric will supply eight new camera units for the first batch of converter stations installed on the State Grid, and six of them will be delivered in the second half of this year.

Tuning camera is a generator that specializes in reactive power. Reactive power is not "useless power", but another form of power supply for electrical appliances. Reactive power can not be directly converted into other forms of energy such as light, heat, etc., but it is the energy necessary for the electrical equipment to establish alternating magnetic fields and induced magnetic flux. Without reactive power, all electrical equipment that requires a magnetic field cannot operate. The size of reactive power and active power together determine the voltage level in the grid line.

In recent years, with the rapid development of UHV AC/DC power grids and large-scale grid-connected clean energy such as wind power and solar power generation, the operating characteristics of power grids have undergone tremendous changes—AC and DC, sending and receiving ends interact, and AC and DC faults. The chain reaction mechanism is complex and brings huge hidden dangers to the safe operation of the power grid. Therefore, adding a new type of modulation camera in the power grid will solve the problem of reactive power and voltage compensation adjustment during its operation, and it will function as a “destination needle” to ensure stable and reliable operation of the power grid.

According to reports, traditional modulation cameras provide reactive power to the grid system under normal conditions, improve the power factor of the grid, and maintain the voltage level of the grid. However, the world’s most advanced modulation camera developed by Haha Motors pays more attention to the transient performance in addition to the aforementioned functions. A large amount of reactive power is output in a very short time, and the short-time over-current and over-voltage capabilities with higher parameters provide more robust protection for the safe and stable operation of UHV grids with higher performance and index requirements. According to a related technical expert from Harbin Electric, there is no precedent in the world for this kind of camera.
