Abstract

Application of new synchronous condenser in UHVDC sending and receiving ends is analyzed in this paper. Firstly, considering technical requirements of UHVDC synchronous condenser, models of synchronous condenser are studied and subtransient/transient/steady characteristics are proposed for different time scales. Then for sending end of Jiuquan-Hunan wind-thermal-bundled UHVDC, application effects of synchronous condenser are discussed from aspects of increasing short circuit ratio, reducing risk of renewable energy overvoltage tripping and restraining steady-state overvoltage. For receiving end of multi-infeed HVDC transmission lines in EastChina, application effects of synchronous condenser are discussed from aspects of increasing multi-infeedshort circuit ratio, reducing commutation failurerisk of multiple HVDC, and improving voltage stability level under severe faults. Lastly, compared with traditional synchronous condenser, equipment advantages of new generation are proposed, such as operation & maintenance, reactive response characteristics, etc, providing technical support for subsequent engineering application.
