Advanced Technologies of Preventive Maintenance for Thermal Power Plants

OVERVIEW: Although thermal power generating facilities are aging, flexible operation in response to changes in the demand for electrical power is required. To extend the life and manage the maintenance of those facilities, advanced preventive maintenance technology is important. For that reason, Hitachi has been grappling with nondestructive inspection, life assessment technology, rationalization technology for scheduled inspections of the boilers, steam turbines, gas turbines and other machinery used in thermal power generation to strengthen preventive maintenance and increase the efficiency of maintenance. Recently, we have been developing products and services for advanced support for maintenance and preservation through the use of IT (information technology) and network technology, going beyond what has previously been available.
