The Function Of The Compensation Device

‌The main functions of the compensation device include improving power factor, reducing line losses, improving voltage quality, increasing the transmission capacity of the power system, reducing equipment capacity requirements, improving equipment utilization, suppressing harmonics, balancing three-phase loads, and enhancing the transient state of the system Stability and adaptability to new energy access. ‌‌

‌Improve power factor‌: By reducing the flow of reactive power, the compensation device can bring the power factor of the power system close to 1, thereby improving the efficiency of electric energy utilization and reducing reactive power losses.

‌Reducing line losses‌: The increase in power factor leads to a reduction in the flow of current in transmission lines, thereby reducing the active power loss caused by line resistance. This is especially significant for long-distance transmission lines, helping to reduce energy waste and costs.

‌Improve voltage quality‌: The compensation device can smooth voltage fluctuations, reduce harmonic content, provide purer and more stable power, and improve the operational reliability and stability of power equipment.

‌Increase the power transmission capacity of the power system‌: Without increasing hardware investment, compensation devices can increase the power transmission capacity of the system to meet the growing power demand.

‌Reduce equipment capacity requirements‌: Due to the reduction of reactive current, the compensation device reduces the capacity requirements of electrical equipment such as transformers, switchgear and cables, saving equipment investment and reducing floor space.

‌Improve equipment utilization‌: The compensation device enables electrical equipment to operate under a more ideal power factor, reducing heat generation and losses, extending the service life of the equipment, and improving equipment utilization and operating efficiency.

‌Suppress harmonics‌: Some compensation devices such as active filters can suppress harmonics in the power grid and ensure the safe and stable operation of the power system.

‌Balance three-phase load‌: In a three-phase power system, the compensation device can adjust the reactive power distribution among the three phases, reduce zero-sequence current and negative-sequence current, and improve power quality and operational stability.

‌Enhance the transient stability of the system‌: When the power system suffers a fault or disturbance, the compensation device can respond quickly and provide necessary reactive power support to help the system restore stable operation.

‌Adapt to new energy access‌: With the large-scale integration of new energy sources such as wind power and photovoltaic into the power grid, the volatility and uncertainty of their output power have brought challenges to the power grid. The compensation device can adapt to this change and ensure the safe and reliable operation of the power grid.
