DEVICE AND METHOD FOR MONITORING THERMAL STRESS OF THERMOELECTRIC POWER STATION

摘要

PURPOSE: A monitoring device of thermal stress in a thermoelectric power station and its method are provided to improve the safety, the reliability and the life length by monitoring the thermal stress and system stress at real time. CONSTITUTION: A monitoring device of thermal stress comprises many temperature sensors(100) to measure temperature; many pressure sensors(200) to measure pressure of main components; instrumentation devices(300) to collect analog operation data, to convert to digital data and to transmit to a client system(400); the client system(400) to transmit digital operation data to a server system(500) at real time; the server system(500) to calculate stress of the main components and to display the calculated data to an operator by receiving the digital operation data. Thereby, the stress and a remained life length of a power station are offered to the operator at real time.
