Compensation Systems

In practice, factories, electrical machinery, construction machinery and engines supply reactive power to the network they connect, as they work inductively. This reactive power causes considerable fall in active power, thus a fall in yield in return. When the same system is compared for uncompensated and compensated states, it is seen that the current drawn does not change, but there is an increase in the active power. A compensation board is connected to the entrance of the inductive system to increase work productivity and to prevent reactive power from affecting the network, so that the reactive power produced in the circuit has been stored in the condensers without going to the network. When the engine starts working, these condensers switch the reactive power they stored back to the engines. Therefore, the network recognizes the system close to a pure resistive one and no reactive power exchange happens between the network and system. Industrial plants with high electricity consumption, if exceed the specified capacitive value, are faced with raised electricity bills, and face losses caused by reactive loads. A well-designed compensation system can provide a saving of up to 25%.
