What are the three main objective of the load compensation?
The main objectives in load compensation are: Improved voltage profile • Power factor improvement • Balanced load.
How is load imbalance calculated?
There are three steps in the calculation:
- Determine the voltage or current average.
- Calculate the largest voltage or current deviation.
- Divide the maximum deviation by the average voltage or current and multiply by 100 % unbalance = (Max deviation from average V or I/average V or I) x 100.
What is the objective of load compensation?
Load compensation is the management of reactive power to improve power quality i.e. V profile and pf. Here the reactive power flow is controlled by installing shunt compensating devices (capacitors/reactors) at the load end bringing about proper balance between generated and consumed reactive power.
What are the advantages of load compensation?
Series compensation has several advantages like it increases transmission capacity, improve system stability, control voltage regulation and ensure proper load division among parallel feeders.
How does phase balancing and power factor correction work?
These devices can be applied to provide power factor correction, three phase load balancing, volt- age regulation, flicker control, harmonic elimination, increased network stability and better con- trol of power flow.
How is a modulated static compensator used for load balancing?
The purpose of this thesis is to demonstrate that a pulse-width-modulated static compensator is capable of performing three-phase load balancing and power factor correction. An unbalanced load is analysed using sequence component theory and a mathematical solution found to satisQ the load balancing and power factor correction requirements.
How is power factor correction used in sequence component theory?
An unbalanced load is analysed using sequence component theory and a mathematical solution found to satisQ the load balancing and power factor correction requirements. Two types of pulse-width modulation to implement this theory are investigated – sinusoidal pulse width modulation and current reference pulse width modulation.
