　　Actively develop power quality control work

　　Power quality management methods are mainly filtering and reactive power compensation, including the use of passive filter and active filter.

　　Passive filter is to provide harmonic low impedance branch for filtering, its existing problems are :(1) a parameter can only be compensated for a specific number of harmonics, and under certain conditions will be resonant with a harmonic to amplify the harmonic, causing other accidents; (2) Slow response speed, unable to track dynamic harmonics, dynamic compensation; ⑶ can only compensate for fixed reactive power; (4) When the system impedance is relatively small, the compensation effect is difficult to meet the requirements; (5

　　ANAPF有源电力滤波装置选安科瑞harmonic component hazard

　　The harm of harmonic component is multifaceted, mainly manifested in the following aspects:

　　1) The harmonic component causes additional harmonic loss to the components in the power network, reduces the efficiency of power generation, transmission and electrical equipment, and increases the loss of the system. (2) Harmonics will cause local parallel resonance or series resonance in the power grid. When resonance occurs, the harmonic component will be amplified several times or even dozens of times instantly. At the same time, a large number of third harmonics flowing through the neutral line will make the line overheat, or even fire, seriously affecting the safety of power grid operation. (3) Harmonic components affect the normal work of various electrical equipment in the system, such as capacitors, cables and other equipment overheating, insulation aging, life shortening and even damage; Harmonics will also cause mechanical vibration, noise and overvoltage of the motor, which will not only cause serious overheating of the motor, but also increase the additional loss of the motor. (4) Harmonics will not only lead to the misoperation of the relay protection and automatic devices in the system, but also make the secondary measuring instrument is not accurate. (5) Harmonic component will produce signal interference to the nearby communication system. At the light level, it will produce noise and reduce the communication quality; at the serious level, it will lead to the loss of communication data and the system can not work normally. (6) Harmonics will cause the temperature of equipment and materials to rise, which will lead to additional loss. Each temperature rise of 1 °C, the motor build automatic environment, with the support of science and technology, to ensure the development direction of distribution network automation. Practice shows that distribution automation and intelligentization can greatly improve the safe operation level of distribution network, improve the quality of power supply, reduce loss and save energy, and make full use of the capacity of existing equipment to reduce people's labor intensity.
