Abstract

The invention discloses an on-line monitoring device based on an F level gas-steam combined unit generator rotor, the on-line monitoring device comprises a position sensor which is electrically connected with the generator rotor and is characterized in that a voltage transmitter is connected to the signal output end of a position sensor, and a real-time monitoring structure of the generator rotoris formed; a signal input end and two signal output ends are arranged on the voltage transmitter, the signal input end is connected with the signal output end of the position sensor, one signal outputend is connected with the control signal input end of a DCS, and the other signal output end is connected with the control signal input end of a fault recorder; the fault recorder is used for recording the data information of the position sensor in the operation process; the DCS is used for monitoring a picture to draw the waveform image-text of the position sensor signals; an image-text type on-line monitoring structure is formed. The on-line monitoring device based on the F level gas-steam combined unit generator rotor has the advantages that the position sensor is monitored in real time and the starting failure is prevented.

Description

technical field [0001] The invention relates to an on-line monitoring device based on a generator rotor of an F-class gas-steam combined unit, which is suitable for the static frequency conversion start of the F-class gas-steam combined unit. It belongs to the technical field of power generation industry and auxiliary equipment. Background technique [0002] The F-class gas-steam combined unit needs to use a static frequency conversion device to drag the unit to a certain speed when the unit starts, so that the gas turbine can increase the speed independently. The static frequency conversion device needs the generator rotor position signal as a static frequency conversion device during operation. Once the position sensor signal fails permanently or loses instantaneously, it will cause startup failure. [0003] At present, the static frequency conversion device of the F-class gas-steam combined unit cannot monitor the signal of the position sensor in real time. When the sign...
