Furthermore, the vibration is still new to large units shipped impossible grid, the normal operation for the main the crew during normal operations, continuous vibration problems affecting the normal production, Units often reduced load and operation of the sick, and even the unit was forced to stand, these incidents not uncommon. The system based on LabVIEW virtual instrument software platform for turbine vibration signal window read, and spectral analysis and correlation analysis. LabVIEW virtual instrument is a common core of computer hardware platform, defined by the user, with virtual front panel, the test function test software from a computer equipment system.
