Abstract
To be used as a normal operation mode, islanding operation at the sending terminal of Yunnan- Guangdong ultra high voltage direct current (UHVDC) transmission system should be able to withstand the impact of various typical faults which can occur during long-time operation. The DC system mono-polar blocking fault is one of the serious faults that the islanding operation must be able to bear. Based on the islanding operation on-site commissioning tests, the testing results of mono-polar blocking fault under the rated DC power operation were analyzed. Using accurate electromagnetic transient simulations of the islanding operation system, the influence of PSS reactive power inverse-regulation of generation units on fault recovery characteristic after the mono-polar blocking were analyzed. The adjustment of power system stabilizer (PSS) output limitations for improving the fault recovery characteristic was evaluated. The analysis provides a technical support for the real system operation using islanding operation modes.关键词
