ANALYSIS OF A TURBINE TRIP TRANSIENT WITH THE CHINSHAN PLANT ANALYZER

To apply fast and accurate simulation techniques to wanese nuclear pow er plants, plant analyzer technology was transferred to Taiwan from th e Brookhaven National Laboratory (BNL) through a cooperative program. The Chinshan plant analyzer was developed based on the BNL boiling wat er reactor plant analyzer. The simulation speed of the Chinshan plant analyzer is eight times faster than real time. The detail analysis pro cess of the turbine trip transient is demonstrated. The self-initializ ation procedure automatically generates the desired plant conditions. These plant conditions are saved in a file and read directly for the s imulation. The simulation is started by inputting the start time of th e turbine trip from the keyboard of a personal computer. The simulatio n results are shown instantaneously on the screen of a Micro-VAX II wo rkstation. A comparison of the calculated system response with the pla nt data indicates good agreement. The sequence of events is also close to that of the test result.
