· What is reactive power's harm?
· 1. Low power factor, fined by government.
· 2. Reduce distribution system effective capacity, need to increase system capacity.
· 3. Increase power cost, low efficiency, increase power loss and equipment get hot.
· 4. Generate voltage drop caused by reactive current, equipment is derated.
· What is benefit of reactive power compensation?
· Avoid low power factor fine
· Reduce power cost, increase efficiency
· Reduce power consumption by reactive power
·
· Release system capacity occupied by reactive power
·
· What is static var generator(STATCOM/SVG)?
· Static var generator is used to improve power factor, through compensating reactive power actively and dynamically.
·
· Static var generator adopts high power three phase voltage type inverter as core, output voltage is connected to electric network through parallel connection with reactor, keeping same frequency and same phase as system side voltage. Through adjusting output voltage and system voltage amplitude relation to determine output power nature and value, realize static var compensation for power dynamic compensation.
