        Monitoring and treatment of power quality problems

        AddTime:2020-12-21 14:22:59   Views:     【 Big Mid Small 】   Print   Close

        Power quality is not only related to the reliability and safety of electrical equipment operation, but also related to the standardization of power supply and consumption market. It may come from the power transmission and distribution system of the power supplier, the unreasonable power consumption of the user, and the natural phenomena such as lightning. Only by effective monitoring of power quality, can we have a deeper understanding of the generation and impact of the problem. Then it provides a real basis for the improvement of power quality, the coordination of power supply and consumption and the regulation of power supply market, so as to take effective measures.

        It is necessary to analyze the power quality of the power grid in real-time, and to monitor the power quality of the power grid Before operation and new power users are put into operation, technical consultation on harmonic source load and power quality requirements should be conducted; in line network reconstruction and construction, the characteristics and measures of operation load should be combined to reduce line loss and equipment loss accidents.

        Power quality on-line monitoring device adopts dual CPU system structure and high-speed processing ability of DSP, which plays a key role in ensuring real-time online monitoring, intelligent, networking and other powerful functions of the system without sacrificing real-time performance. It has the characteristics of on-line monitoring, high accuracy, great upgrade potential, good real-time performance, small size and low cost. It is not only suitable for on-site potential analysis, but also suitable for long-term online monitoring.

        The measures to improve the power quality also depends on the installation of some equipment, so as to improve the power quality and enhance the stability, such as: static var compensation device, reactive power generator, active filter, select these equipment for harmonic control.
