Analysis on the Saving Rate Test of the Frequency Converter in Power Plant

In order to increase the energy-saving rate and reduce emissions, the power generation enterprises generally use the frequency converter to control part of high-voltage motors. After the power generation was put into operation, many power generation enterprises are unable to correctly monitor and evaluate the power saving effect of high-voltage motor frequency converter, so it is necessary to evaluate the power saving effect of high-voltage motor frequency converter. At present, there are many methods to test and evaluate the power-saving effect of frequency converter. At present, the power-saving rate of frequency converter is usually used to characterize the power-saving effect of frequency converter. The so-called power saving rate is the percentage of the power consumption saved by the application of variable-frequency speed drive system and the power consumption of the system without the application of variable-frequency speed control device in the same specified operation cycle, when the terminal needs are met, the environmental conditions are similar, and the operation conditions are the same.
