ZD-CSVG-2000 dynamic hybrid reactive compensation device consists of two parts – static reactive generator unit and switching capacitor / reactor reactive compensation unit. In ZD-CSVG-2000 hybrid dynamic reactive compensation device, each unit is designed and produced in the method of low power, small volume and low cost, and both of them are optional, and can be combined in the best and flexible way according to the actual reactive state of the site, so as to achieve the optimum ratio of operation effect and cost.
Typical Design
The reactive compensation is usually configured on the basis of 30% of the transformer capacity, for example, 400KVA transformer is usually configured with 120kvar-capacity reactive compensation device, and in special cases, first test the power quality, and then confirm the configuration capacity according to the test result.
SVG module and capacitor capacity in the compensation capacity can be configured flexibly, to achieve the optimum compensation effect.
