Conference Article: Control System of NPP with GT-MHR Power Unit

Abstract

GT-MHR reactor plant (RP) is a prototype of new modular helium reactors with a direct gasturbine cycle. The requirements of competitiveness as compared with alternative types of commercial electric power stations are made for GT-MHR RP. These main requirements are economy, manoeuvrability and safety. NPP power unit with GT-MHR RP as an object of control is distinguished by a number of features, determining special requirements for control arrangement in operation modes and for structure and composition of monitoring and control systems (MCS). Thus, the use of one circuit of coolant circulation requires introduction of additional working members to control balance of capacities in the mode the fast change of capacity, the arrangement of a generator, a turbine and compressors at one shaft determines the necessity to introduce additional systems to control power transfer process to keep the required dependences of temperatures on capacity. MCS of power unit is built as hierarchical distributed system consisting of different subsystems. These separate subsystems are integrated in a unified system on the basis of the all-unit data transmission network, information and calculation system, main control room.
