Reactive power compensation and harmonic control

As the necessary consumption cost of the enterprise, electric energy is directly related to the economic benefits of the company. The main purpose of the company's distribution system is to reduce losses and save energy, improve the voltage quality of the power grid, save energy and reduce consumption, and effectively ensure the production and operation of the company.

In the process of production, the existence of a large number of reactive loads in the power system and the loss of a large number of reactive power in the process of system operation will greatly affect the quality of production power and cause intangible waste. In order to improve the utilization rate of electric energy, ensure the quality of electric energy and minimize the loss of electric energy, since June, the company has installed reactive power compensation devices on the 10kV side of 35kV distribution room, and installed three reactive power distribution cabinets and harmonic processing devices, each of which is 1000kvar. Harmonic treatment is carried out on 270 and 370 internal mixer respectively to reduce the consumption of reactive electric energy. After installation, the amount of reactive power consumption and harmonic generated during the working process of the internal mixer in the internal mixing workshop was measured. Remarkable results were achieved in only two days. The reactive power factor was improved, and the reactive power consumption was significantly reduced, down by 35%. Compared with the ring period, the company can save 30% of the electricity charge per month

The company is equipped with reactive power compensation facilities, and the power factor has been significantly improved, which not only saves a lot of electric energy and reduces the production cost, but also reduces the line loss, improves the power quality, balances the three-phase power, provides voltage support for the company's power system, and improves the system operation, production efficiency and safety.
