| description | The paper describes a model that confirms the reliability of the diagnostic methodology for the drives of the control and protection system (CPS) of the power units. The model simulates the operation of the diagnostic object which generates signals that are recorded, stored and processed by the Diagnostic System of the CPS drives. This system was developed by MEPhI as a pilot sample designed to diagnose the drive of the ARC of the fourth block of the Novovoronezh NPP and the drive of the LSD of the fifth block of the Novovoronezh NPP. The main requirement for the system is the ability to identify the most common defects in the drives of the ARC and LSD. The system has versatility, mobility, compactness and ease of use, and its technical and economic indicators are higher than the patented objects of industrial property, which indicates the prospects of its use for monitoring the technical condition of the electric drives of CPS in order to improve the safety of NPP. A methodology is developed which establishes the requirements for the content and organization of the procedure for diagnosing CPS drives using a comprehensive information system for monitoring the technical condition and resource characteristics of CPS drives of power units of the reactor WWER-440. This technique applies to the drives of CPS of the ARK and LSD type, which are in operation at nuclear power plants and is intended for specialists who use diagnostic system of CPS for their intended purpose. Validation of the methodology underlying the operation of the system is carried out by processing signals simulating the operation of drives in conditions of the most common defects. The article provides examples of simulated signals containing signs of defects provided by the methodology. The introduction of a validated system and methodology will simplify the task of collecting, analyzing, and comparing data on drives during operation at nuclear power plants, and will also improve the qualifications of personnel, which should have a positive impact on increasing the reliability and resource of equipment. |
