How reactive power is helpful to maintain a system healthy

    When reactive power supply lower voltage, as voltage drops current must increase to maintain power supplied, causing system to consume more reactive power and the voltage drops further . If the current increase too much, transmission lines go off line, overloading other lines and potentially causing cascading failures.

Reactive power services National Grid ESO

    Reactive power services are how we make sure voltage levels on the system remain within a given range, above or below nominal voltage levels. We instruct generators or other asset owners to either absorb or generate reactive power.

What Is Reactive Power and Why Does It Matter?

    https://business.directenergy.com/blog/2016/may/reactive-power
    Reactive power is either generated or absorbed by electric generators (or, in some cases, devices known as "capacitors") to maintain a constant voltage level, commonly referred to as providing “voltage support.” Generators providing voltage support often suffer heating losses that result in a reduced ability to generate “real” power.

Reactive Power Compensation - Electrical idea

    Dec 20, 2016 · Reactive power must be supplied to most types of magnetic equipment, such as motors and transformers. In an ac transmission, when the voltage and current go up and down at the same time, only real power is transmitted and when there is a time shift between voltage and current both active and reactive power are transmitted.Author: Sohalsinh Chauhan

    Reactive power loads must be supplied either locally from customer-owned devices or from the system itself. It is almost universal for some of the reactive load to be compensated locally as power-factor correction. Power factor is a measure of the relation between real and reactive power. The power factor ranges from 0.0 to 1.0, where 1.0 means ...

Voltage support Transpower

    https://www.transpower.co.nz/system-operator/electricity-market/voltage-support
    Voltage support is provided by generating units or static equipment capable of producing or absorbing reactive power. This is done to maintain voltages on the system within Code limits. We may enter into voltage support contracts with parties who can offer voltage support compliant with our technical requirements and the Code.
