Research of Modulation of Bilateral Frequency Difference Based on Load Mode
摘要：Owning to high reliability, simple operation and easy acquirement of signals, modulation of bilateral frequency difference（MBFD） in HVDC is worthy for application in practical engineering. With the example of an AC/DC hybrid network and the software PSDBPA, this paper analyses the effect of MBFD to DC block. The modulators parameters are setting by means of simulation. Two types of loads modes are considered to research the impact of them on simulation. The results indicate that in cooperation with operation modes adjusting at AC system, MBFD will effectively release the impact from DC block and shortage of reactive power caused by rapid variation of DC power owning to modulation. To achieve the best effect, only modulators of some HVDC systems instead of all of them are opened.
