Three-Phase Compensation Capacitor

When designing a centralized compensation scheme for a low-voltage power distribution system, how to scientifically calculate and determine the total capacity of the Three-Phase Compensation Capacitors is the crucial first step that determines the success or failure of the power project. As Geyue Electric, a solution provider with a long history in the field of low-voltage reactive power compensation, we truly understand the importance of accurately calculating the total capacity of the capacitors before their implementation. Therefore, this article will guide you step by step through the core methods for calculating the total capacity of the capacitors, ensuring that the internal design of your low-voltage reactive power compensation cabinet can achieve the best performance.

All calculations begin with a given compensation prerequisite and a clear compensation goal. Before applying the three-phase compensation technology, one prerequisite that you need to confirm is that the three-phase load of your power distribution system must be relatively balanced. This important prerequisite is very common in industrial plant scenarios where three-phase motors are the main load. After confirming that the scenario conditions meet the prerequisite for three-phase compensation, your compensation goal should be clearly defined as increasing the power factor of the power system from the current relatively low level to the level encouraged by the national power supply department, for example, reaching 0.95 or higher. Achieving this goal not only avoids electricity penalty fines due to non-compliance with the power factor, but also effectively reduces losses in lines and transformers, releases power supply capacity, and brings direct economic benefits. The BSMJ series Three-Phase Compensation Capacitors developed by Geyue Electric’s R&D engineers is a classic series of products designed to help you achieve this goal.

The core of calculating the total compensation capacity lies in a classic formula: the required compensation capacity = system active power × compensation coefficient. Specifically, you first need to obtain the monthly average active power (in kilovar) from the power bill or power monitoring system, as well as the existing natural power factor. Then, based on the target power factor, you can get a specific compensation coefficient value by referring to the industry-standard compensation coefficient table in your field. As long as you multiply the average active power by this coefficient, you can initially determine the total reactive compensation capacity of the Three-Phase Compensation Capacitors required. To simplify this process, the technical team of Geyue Electric is always ready to provide you with free calculation services and technical support, with a promise that your basic data will be totally accurate under our full supervision.

The theoretical value of the total compensation capacity of the Three-Phase Compensation Capacitors calculated by the classic formula is only the basis. An excellent reactive power compensation solution must take into account the actual reactive power demand in the engineering. We strongly recommend that you reserve 10% to 15% of capacity margin based on the calculated theoretical value. This margin is intended to cope with the possible increase in reactive power demand in the power system due to the expansion of production scale in the future, so that your low-voltage reactive power compensation cabinet has certain scalability and avoids having to spend funds to retrofit the compensation cabinet or purchase new capacitors again in the near future because of the need to increase capacity. Finally, if you choose Geyue Electric BSMJ series Three-Phase Compensation Capacitors, you can divide the determined total capacity value with the standard capacity of a single capacitor to obtain the specific number of BSMJ capacitors required for your compensation system. At this point, congratulations! You have completed the final determination of the total capacity of the Three-Phase Compensation Capacitors for your centralized compensation cabinet.

Once the calculations are completed and the blueprint is drawn, choosing a high-quality capacitor brand is the final step in converting theory into reliable practice. Geyue Electric sincerely recommends to you our independently manufactured BSMJ series Three-Phase Compensation Capacitors.
