An optimal solution for efficiently compensating the capacitive reactive power is to install shunt reactors for both medium and high voltages. GBE can supply a wide range of oil and cast resin reactors.
The development of long-distance MV and LV transmission networks, as well as underground cable lines, has caused an increase in capacitive reactive power with an ensuing unwanted voltage increase, especially in low load conditions.
Over the past few years in particular, renewable energy stations - wind farms and solar parks, for example - have further increased the capacitive reactive power because of the outstanding quantity of cables installed. These powers are expensive for consumers, and network operators do not want them. For this reason, counterbalancing this production with an inductive compensation system is essential when managing these renewable energy parks with a high-capacity characteristic, especially when working with no load.
Note that if, on the one hand, the limit values for the request of capacitive reactive current are part of the contracts between network operator and consumer, on the other hand the compensation induction systems of the reactive power are generally required in the network node even before commissioning the renewable energy park because of technical regulations and pertinent laws on connection.
An optimal solution for efficiently compensating the capacitive reactive power is to install shunt reactors for both medium and high voltages. Shunt reactors can compensate this capacitive load, but can also maintain an acceptable voltage level that remains within the limits that are compatible with network insulation, limit the transitory overvoltages that are induced by commutation, and reduce line loss by reducing the capacitive current.
GBE can supply a wide range of oil and cast resin reactors. Our strong experience in producing shunt reactors was repaid also in 2023, the year in which 27 shunt reactors immersed in mineral oil or FR3 were supplied to northern Europe. The quality of our products is recognised worldwide: many shunt reactors have even been supplied to the Asian and South American markets.
