EVKompensation

EVKompensation is a term often encountered in the context of energy management and electrical engineering. It refers to the process of compensating for the reactive power component of an electrical load. Reactive power, distinct from active power (which performs useful work), is the power that oscillates back and forth between the source and the load. While not directly consumed, it is necessary for the operation of certain electrical devices like motors and transformers, as it establishes and maintains magnetic fields.

However, excessive reactive power can lead to several inefficiencies. It increases the total current flowing in the system, resulting in higher losses in transmission lines and transformers due to increased resistance. This also reduces the capacity of the power system to deliver active power. Therefore, EVKompensation aims to mitigate these negative effects.

The compensation is typically achieved by installing capacitors or synchronous condensers, which generate leading reactive power to counteract the lagging reactive power consumed by inductive loads. This helps to improve the power factor, which is the ratio of active power to apparent power. A power factor closer to unity (1) indicates a more efficient use of electrical energy. By reducing the overall current, EVKompensation can lead to significant cost savings through reduced energy losses and potentially lower electricity bills, as many utility companies charge for reactive power consumption or penalize low power factors. It is a crucial aspect of maintaining a stable and efficient electrical grid.
