Cost-effectiveness of hybrid and unified compensators of nonactive power in networks

The components of nonactive power in a power system can be compensated separately by different switching convertors, or simultaneously by one convertor. Costs of compensator components and the operational costs are discussed for both cases. The estimates are made based on data of physical compensating systems. The hybrid compensator consists of fixed capacitors, a thyristor controlled reactor and a force compensated six pulse bridge voltage-fed converter.
