Untitled Document
Objectives General Objectives
increasing the technological competence and promoting the knowledge transfer in the field of technological reliability in the field of thermal power production by creating a representative and complementary consortium on the proposed issues;
bringing in a considerable contribution, based on the programmable logic technology, to resolving the complex issue of the power reliability in thermal power plants.
Specific Objectives
elaborating a review on the lifetime of the protection/reliability system for thermal power plants finalized with the generation of a detailed model (a starting point is represented in Fig. 1 below);
defining the security functions during the elaboration of the hazard analysis and risk evaluation;
data collecting on the frequency of dangerous events, the evaluation of the consequences
detail design of the functional model, estimated at a number of 64 digital signals, 12 analogue signals and 24 digital outputs for decoupling;
evaluating the response time for decoupling commands including the longest duration of taking over the logic in the central unit;
designing a predefined event recording system;
designing at least 8 complex derived events (logic signals combination);
generating a calculating method for the performance evaluation parameter (PFD, RRF, SA, SIL);
the acquisition from suppliers or from statistical reliability data sources for sensors and actuators;
the physical execution of the functional model and its testing by event simulation;
the analysis of the control parameters for the acquisition of which they will provide the connecting line monitoring function;
providing the redundant supply sources likely to ensure the automatic switch without damaging the control process;
the analysis of the fault detection possibility on the hardware side and the analysis of the possible effects regarding the false decoupling;
designing the principle and detail structure of the integrated system;
