Probabilistic Method and Model for the Intermodular Interaction Parameters Estimating in Vibration Protection Control Systems of Turbine Units

Abstract

The paper briefly describes the structure of a turbine unit's modular vibration protection control system (VPCS), formulates the problems of estimating the intermodular interaction parameters that arise at the early stages of VPCS design. Based on the algorithm analysis for the operation of various CANopen protocol services, a probabilistic method is proposed for determining the main communication processes parameters in the VPCS using the queuing theory elements. The mathematical model of the VPCS using the proposed method is considered, its input parameters, the functioning algorithm and output data are described. A technique for studying a real VPCS using a model is described, the results of modeling are presented, their analysis is carried out, based on which methods for optimizing some parameters of intermodular interaction are proposed.
