“…For weak AC systems, it is necessary to install static var compensators or synchronous compensators. [35] When the HVDC system deblocks, if the minimum number of AC filters are suddenly added, the reactive power consumed by converters will be much less than the reactive power supplied by AC filters, thereby resulting in the reactive-power impact on the AC system and causing AC-voltage fluctuation. If the HVDC system operates at low load, adding the minimum number of AC-filters will lead to surplus reactive power and thus it is very difficult to regulate AC voltage.…”

This paper discuses the performance of the SVC ( Static Var Compensator ) linked to the inverter side of ChinaRussia 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, the interaction between SVC and BTB-HVDC is analyzed, and the effectiveness of the coordinated control strategies is verified.

The reactive power compensation of converter station plays an important role in the design of HVDC project. Reactive power configuration for HVDC converter station is introduced in this paper. The regulation and control of reactive power and devices are considered from both steady-state and dynamics aspects. The performance of various reactive power configuration methods are compared and summarized. The principle, characteristics and application of shunt and series reactive power compensation device and a brief description of the reactive power support capacity of AC system are given. The adjustment of transformer tap changer and firing angle can also affect reactive power level. It comes to a conclusion that proper reactive compensation devices should be chosen carefully in converter station, and AC system reactive support capacity and the behavior of HVDC system must be fully taken into consideration when the comprehensive configuration of reactive power of converter station is determined.
