Research About Software Verification and Validation of Control and Protection System for Chinese Heavy-Duty Gas Turbine

Abstract

With the development of digital and intelligent technology in industrial control, the safety and reliability of control and protection system is becoming increasingly prominent. As the Pearl of modern industry, heavy duty gas turbine is very important. The ongoing independent R&D work of UGTC (China United Gas Turbine Technology Co., Ltd.) has been highly concerned by the industry. As the nerve center system of gas turbine, whether the control and protection system can complete the expected function safely and reliably is also an important part of the independent R&D work of heavy-duty gas turbine. In this paper, combined with the independent research and development experience of nuclear power control and protection system in China, based on the functional safety certification requirements of IEC 61508 standard, the technical scheme of heavy-duty gas turbine control and protection system software V&V is discussed, and the relevant technical key points are put forward, which has a certain guiding significance for the design and commissioning of control and protection system of heavy-duty gas turbine.
