Abstract
An automatic three-phase unbalanced load compensation experimental device includes an automatic compensation device, a load simulation part, and detection, display and control parts. The automatic compensation device includes power capacitors and intelligent grouping compound switches. The detection, display and control part includes a plurality of current transformers, molded case circuit breakers, a three-phase digital display ammeter, a three-phase electric power monitoring instrument, a protocol conversion module, RS-485 buses, Ethernet cables and an upper computer. The load simulation part includes phase A, B and C loads which are in star connection and are same in component and circuit connection, an analog output module and a relay output module. A power monitoring instrument and digital ammeter are connected to the grid by circuit breaker and the plurality of current transformers. The automatic compensation device and load simulation part are connected to the grid in parallel.
