Abstract

Abstract:

In order to avoid the power plant tripping due to low voltage disturbance of the power plant which triggers the protection action of the unit, the test of the influence of low voltage on the converter of the coal feeder was carried out according to the specific conditions of the equipment of Zhejiang Energy Lanxi Power Generation Company Limited. It proposed a method of low voltage ridethrough for coal feeder frequency converter of directfiring pulverizing system with middle speed mill.

Key words:

coal feeder, frequency converter, low voltage ride through
