In the operation of power systems, the optimization of power factors is a key factor to ensure efficient energy utilization and stable operation of equipment. Power factor, as an important parameter to measure the efficiency of power systems, reflects the ratio of active power to reactive power in power and directly affects the energy consumption and load capacity of the power system. Ideally, the power factor approaches 1, which means energy utilization is close to perfect. However, in actual operation, the power factor often decreases due to various factors, which in turn causes energy waste, increases grid load, and damages electrical equipment. Therefore, taking effective power factor compensation measures is not only a need to improve the efficiency of the power system, but also an important means to ensure the reliability of the power system.
Passive power factor compensation technology
Passive power factor compensation technology improves the power factor by installing passive components such as capacitors and inductors. Its main advantages are simple structure, low cost and easy maintenance. This technology mainly includes the following methods:
Parallel capacitor compensation: As the most common method of passive compensation, capacitors are connected in parallel in the power system and the reactive power provided by the capacitor is used to offset the inductive reactive power in the system, thereby improving the power factor of the entire system. Capacitor capacity selection and adjustment should be based on the actual needs of the load to achieve the best compensation effect.
