Abstract

The controllable high resistance of the 750-kV transformer substation bus in D is the first controlled high resistance of the 750-kV voltage level, which is due to the lack of actual operating experience. The controllable high resistance in airdrop and capacity adjustment will produce harmonic voltage or current at different levels and of different frequencies, which may threaten the stability and safety of system operation and equipment seriously. In this chapter, the controllable high resistance during airdrop and run adjustment are studied by recording the electrical quantities and analyzing the harmonic. The effect of the second harmonic to the high-voltage direct current (HVDC) system and the hazards of the direct current (DC) component to the reactor are adjusted to obtain the harmonic characteristics of the controllable high resistance of the 750-kV transformer substation bus in D. Based on the above analysis, some recommendations are made to maintain the controllable high resistance of the 750-kV transformer substation bus in D so as to alleviate the frequent switch of reactive power compensation equipment as a result of high voltage and stochastic volatility.
