Abstract
In this paper, the thermal power plant is taken as the research scenario,andthe general research steps of the influence of voltage sag on process parameters are put forwardbased on PIT basic theory. According to theanalysis oflossvoltageandloss power,the loss energy is calculated. Finally, the change of process parameters isfiguredout.So the relationship between loss voltage, loss power, loss energy and process parameterscan beobtained. In addition, through the analysis of the process of combustion system in thermal power plant, the influence of energy storage links and process time constants on thechangingof process parameters intime and extentduringthe process of voltage sag is analyzed.At last,the selection principle of compensation energy and compensation time in the process of sag treatment is pointed out, and theDC side parallel energy storage compensation is proposed for frequency conversion auxiliary units in thermal power plantas thevoltage sagmitigationmeasure.
