Abstract
With the wide application of power electronic equipment in modern power system, the problem of harmonic pollution and reactive power becomes increasingly prominent, which seriously affects the stable operation and power quality of power system. As an important means to improve the performance of power system, harmonic control and reactive power compensation have become one of the hot research topics in the electric power industry. This paper deeply discusses the harmonic control and reactive power compensation technology in power system, analyzes its principle, application and importance, and puts forward the corresponding solution and optimization strategy. This paper expounds the necessity and principle of harmonic control. Harmonics refers to the distortion of voltage and current waveforms in power systems, resulting in voltage and current components whose frequencies are integer multiple fundamental frequencies. Harmonics not only cause equipment heating, vibration and noise increase, but also cause power grid voltage fluctuations, reduce power quality, and even damage power equipment and interfere with communication systems. Therefore, harmonic control is of great significance to ensure the safe and stable operation of power system. This paper introduces the main methods of harmonic control, including using passive filter and active filter to suppress or eliminate harmonics, and optimizing the control strategy of power electronic equipment. This paper discusses the function and principle of reactive power compensation in power system. Reactive power compensation is through the installation of reactive power compensation equipment in the power system, such as capacitors and inductors, to balance the reactive power in the grid, so as to improve the voltage quality, reduce line losses and improve the operation efficiency of the power system. Reactive power compensation can improve the power factor of the system, reduce the transmission of reactive current in the grid, thus reducing the loss of the grid and improving the voltage stability. This paper analyzes the application status and development trend of reactive power compensation technology, including traditional compensation methods such as shunt capacitor, synchronous adjusting camera and static reactive power compensator, and modern reactive power compensation devices based on power electronics technology. This paper presents a comprehensive application strategy of harmonic control and reactive power compensation in power system. In view of the harmonic pollution and reactive power problems existing in power system, we should consider the demand of harmonic control and reactive power compensation, and formulate a scientific and reasonable comprehensive treatment scheme. By optimizing the control strategy of power electronic equipment, rationally allocating reactive power compensation equipment and adopting advanced harmonic control technology, the harmonic and reactive power in power system can be effectively controlled, and the overall performance and operation efficiency of power system can be improved.
