The compensation methods of parallel power capacitors can be classified according to the installation location into which of the following types?
Aug 06, 2025| Ⅰ. Centralized compensation at substations
1. Main advantages and features:
Improve the power factor of the substation
Reduce the reactive power loss of the main transformer
Easy management and maintenance
2. Applicable Scenarios:
Industrial areas with concentrated load distribution
The outgoing lines of the substation are mainly composed of resistive loads.
Overall improvement of power supply quality is required.
II. Distributed Compensation of Lines
1. Technical Value:
Reduce line voltage loss
Optimize the voltage distribution along the line
Reduce reactive power transmission in the lines
2. Typical Applications:
The rural power grid with a longer power supply radius
The load is distributed evenly along the line.
The area with low terminal voltage
III. On-site Compensation at the User Side
1. Core Advantage:
The compensation effect is the most accurate.
Reduce internal losses among users
Does not occupy system capacity
2. Applicable Objects:
High-power electric motor
High-frequency operation equipment
Large electromagnetic device
