6시그마 기법을 적용한 원자력 터빈 시뮬레이터의 발전기 출력 연산오차 저감

다국어 초록 (Multilingual Abstract)

This paper describes the improvement of the calculation by using 6σ method on steam turbine simulator in a nuclear power plant. The simulator is essential to not only verification and validation of control logic but also making sure of control constants in upgrading the long time used control system into the new one. And the dynamic model is a key point in that simulator. The model used during the retrofit period of the turbine controller in Kori Nuclear Power Plant makes difference in calculating generator output and control valve positions. That is because such operating data as the main steam pressure, the main steam temperature and control valve positions of Yongkwang #3 are different from those of Kori #4. Therefore, the model parameters must be tuned by using actual operating data for the high fidelity of simulator in calculating the dynamic characteristic of the model. This paper describes that the 6σ method is used in improvement of precision of generator output calculation in the steam turbine model of the simulator.
