The UPQC is considered the most powerful CPD as it combines both converters via a common DC link.
Static Transfer Switch (STS), Static Current Limiter (SCL), Static Circuit Breaker Fast switching for fault isolation and rapid load transfer.
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)
Available with or without energy storage; storage-based models use batteries or capacitors to provide the necessary active power for compensation. 2. Distribution Static Compensator (DSTATCOM) The UPQC is considered the most powerful CPD
Power factor correction, load balancing, and mitigating current-related harmonics. 3. Unified Power Quality Conditioner (UPQC)
It supplies or receives reactive power at the point of common coupling. Unlike Flexible AC Transmission Systems (FACTS) which focus
DSTATCOM is a voltage source inverter (VSI) that maintains bus voltage at required levels.
