This paper discusses the performance of the SVC ( static var compensator ) linked to the inverter side of China-Russia Heihe BTB (back-to-back) HVDC project. Detailed Heihe BTB-HVDC primary system, China side AC 500/220kV electromagnetic loop network, the control system of BTB-HVDC and SVC are modeled using the electromagnetic transient simulation software PSCAD/EMTDC. Based on the detailed models,...
In this paper, load compensation using multilevel inverter-based distribution static compensator (DSTATCOM) is presented. The DSTATCOM is connected to a three-phase four-wire (3p4w) distribution system. Two different multilevel inverter topologies are used to realize the DSTATCOM. They are diode-clamped multilevel inverter (DCMLI) and flying capacitor multilevel inverter (FCMLI). A compensating technique...
This paper deals with special active power line conditioner (APLC), which is based, the same as UPQC, on integration of series and shunt power converters sharing a common DC link. In this paper the main purpose of the shunt inverter is to compensate the reactive power and current harmonics caused by nonlinear load. In addition, a simple structure feed forward neural network is presented for the separate...
