Abstract
Coordinated control between reactor and turbine is taken by Co-commissioning test between turbine governing system (GRE) and reactor rod position control system (RGL). Matching and completeness of interfaces between reactor and turbine could not be verified by static verification methodology before the unit starts up. Characteristics of coordinated control are analyzed in pressurized water reactor plant. Simulation Co-commissioning test program by static and dynamic verification methodologies between turbine governing system and rod position control system is put forward based on functional classification of interfaces signals. Static characteristics of interface signals between GRE and RGL are checked to verify static matching and completeness of interface signals by simulating the steam turbine to run under various operating conditions in verification method of static simulation. Dynamic response characteristic parameters of interface between GRE and RGL are analyzied and computed to verify dynamic matching and completeness of interface functions by simulating GRE and RGL to run under 4 typical coordinated control operating conditions in verification method of dynamic simulation. The case results have shown that matching and completeness of coordinated control interfaces between reactor and turbine can be verified efficiently by applying the test program into nuclear power plants successfully. And dynamic logic problems of interface are discovered and solved before the unit starts up.
