Medium Voltage Capacitor Bank For Power Factor Correction

Medium Voltage Capacitor Bank for Power Factor Correction

Apr 10,2023

Medium voltage reactive power compensation begins with developing a project that meets customer requirements. ZDDQ has extensive experience in developing various types of MV compensation projects. We fully communicate with each customer who has reached cooperation, and manufacture on time according to customer needs.

The picture below is a set of 3000kvar medium-voltage capacitor cabinets that we installed in a steel industrial park in Southeast Asia:

When and where to compensate at MV?

Basically MV must be compensated when working with:

Generation, transport and distribution systems

The usual points where power factor correction is carried out are the feeder lines of power generating plants (wind farms, hydroelectric installations, etc.), receiver or distribution substations, and distribution hubs.

Industrial installations with MV distribution and consumption

As a general rule, installations that distribute and consume energy at MV are eligible to be compensated, such as pumping centres desalination plants, paper factories, cement factories, the petrochemical industry, steel mills, etc.

Industrial installations with MV distribution and LV consumption

Normally LV compensation is carried out when dealing with small amounts of power and with a rapid demand fluctuation level in comparison with MV. However, if there is a large number of transformer substations and high reactive energy consumption but little load fluctuation, power factor correction at MV should be proposed.
