Abstract
The paper presents a novel method of the reliability increase for safety system (overspeed protection system) for the high-speed steam turbine. Reliability increase is achieved by use of the intelligent mechatronic module with overrunning clutch, and the increase of the number of mechanical overspeed trip mechanism inspections compared with the present regulation. The proposed design allows for safety system testing by the rotation frequency increase of normally running equipment that is radically different from prototypes. This solution application gives the possibility to abandon the existing practice of acceleration to the maximum permissible turbine rotation frequency that ultimately increases its lifetime. In contrast to its prototypes, the test can be carried out automatically without operator intervention. It gives the possibility for application of visual spectroscopy method as a complementary tool to detect a defect, affecting the performance of the proposed system, even on a running turbine. There are no currently existing prototypes of such system that can identify defects before the mechanical security system is tested. The proposed technical solution can serve as a good alternative to costly electronic security systems in the current economic climate. At the same time, the problem of achieving the necessary reliability of the turbine will be solved.
Keywords: mechatronic module, mechanical overspeed trip mechanism, high-speed equipment
