PERUPS (PERFORMANCE UPGRADE SYSTEM) FOR ON-LINE PERFORMANCE ANALYSIS OF A NUCLEAR POWER PLANT TURBINE CYCLE

PERUPS (PERFORMANCE UPGRADE SYSTEM) FOR ON-LINE PERFORMANCE ANALYSIS OF A NUCLEAR POWER PLANT TURBINE CYCLE

We developed the PERUPS system to aid the on-line performance analysis for the turbine cycle of the YongGwang 3 and 4 nuclear power plants. Procedure of measurement validation is included in the performance calculation to obtain heat balance. Precision of on-line performance calculation is increased via practical modifications of standard calculation algorithms based on the PTC (Performance Test Code). The proposed system also provides useful Web-based aids for performance analysis, including performance data management, a graphic viewer for heat balance and turbine expansion lines, and synthesized reports of performance.
