The UPQC is considered the most powerful CPD as it combines both converters via a common DC link.
Power factor correction, load balancing, and mitigating current-related harmonics. 3. Unified Power Quality Conditioner (UPQC)
are a new generation of power electronic controllers designed for medium to low voltage levels (typically 1 KV through 32 KV) to ensure high-quality power delivery. Unlike Flexible AC Transmission Systems (FACTS) which focus on high-voltage transmission, CPDs are specifically applied at the distribution level to protect sensitive consumer equipment. Classification of Custom Power Devices power quality enhancement using custom power de...

DSTATCOM, Dynamic Voltage Restorer (DVR), Unified Power Quality Conditioner (UPQC) The UPQC is considered the most powerful CPD
Custom power devices are broadly categorized into two types based on their function in the distribution network: Device Examples Primary Function
It injects a synchronized voltage into the distribution feeder to maintain a constant load voltage during source disturbances. Unified Power Quality Conditioner (UPQC) are a new
Static Transfer Switch (STS), Static Current Limiter (SCL), Static Circuit Breaker Fast switching for fault isolation and rapid load transfer.
