Power factor improvement methods and correction is one of the crucial aspects to ensure that the appliances are not drawing more current for executing the same amount of work, which is possible with less current consumption. It is one of the most common terms that is used for defining energy efficiency.
Power factor is used to define the efficiency of the electrical systems and is mostly done in the case of AC systems. It needs to be close to unity at all times to ensure that the system is high efficiency. In case the power factor drops to 95%, the current power demand will increase, which will hamper the efficiency quotient of the system.
Therefore, seeking the use of active and passive power factor correction filters is highly essential. Apart from that here are some of the methods or ways to correct the power factor.
Use Of Static Capacitors
The first amongst the several power factor improvement methods is to use static capacitors; these capacitors have the potential to control the current lagging effects. That occurs due to the presence of excessive inductive loads. Static capacitors, when installed parallelly with the equipment that is probably running on a low power factor, will enhance the power factor quotient.
The use of static capacitors will use the leading current to neutralize the lagging current in the system and will correct the reactive component of the load current. It is easy to install, and the losses are low, which ensures less maintenance hassle.
However, you might have to change the static capacitors after every 8-10 years as it is the maximum age for them to handle the fluctuations. Along with that, with the increase in rated voltage, the capacitors might experience damage. Therefore, you need to keep a watch on that!
Use Of Synchronous Condenser
Make use of a three-phase synchronous motor that has the potential to run on no-load. This complete setup is known as synchronous condenser which can operate on unity, lagging and leading power factor rating.
Due to the presence of the inductive load, the synchronous condenser will be installed onto the side of the load. Hence, it will behave as a capacitor for correcting the power factor of the system. The best part of using the setup of the synchronous condenser is that it lasts for up to 25 years without much need for maintenance. Along with that, it also stays unaffected by the harmonics of the system.
Use Of Phase Advancer
Phase advancer is the last and the most effective method for correcting the power factor as it uses an AC exciter for the correction aspects. It is connected to the motor’s rotor circuit to enhance the ampere-turns. It can help obtain a leading power factor as well with higher ampere-turns. The only drawback for this method is that the motors are below 200 H.P. cannot integrate it.
Conclusion
The three crucial power factor improvement methods, which are widely preferred by the industries to ensure energy efficiency and cost-saving in the long run. There are many more economical methods available within the market, such as power factor correction filters to get it done more efficiently.
