Generator Output Regulation
Give priority to utilizing the reactive power output capacity of generators to make up for the deficit
Hierarchical Compensation Deployment
Centralized compensation: Install automatic switching capacitors on substation busbars
Group compensation: Add capacitors on the secondary side of distribution transformers
Local compensation: Configure independent compensation devices for high-power equipment
Dynamic Compensation Technology
Large-scale power stations adopt SVG/SVC (response time ≤20ms)
Enable ±20% power factor adjustment for photovoltaic inverters
Gap in photovoltaic systems:
Link compensation equipment at photovoltaic grid-connection points
Adopt high-voltage sampling + low-voltage compensation to address adaptation issues
Transformer no-load condition:
Intelligent controllers allow no-load over-compensation
Install adjustable capacitors on the high-voltage side
Equipment Maintenance:
Unify the brands and parameters of capacitors
Set the controller delay to 0.5-2 minutes
Harmonic Control:
Over-compensation Correction:
Inspect the wiring of power factor meters
Precisely control the input capacity of capacitors
Shorten the no-load operation time of equipment
Implement cloud-based real-time monitoring of power factors
