The modular multimicroprocessor system architecture for the power turbine control

The modular multimicroprocessor control system (MMCS) architecture for turbine control is presented. The turbine features which are produced by “Metalicheskiy Zavod” plc (St.-Petersburg) are considered. The multilayered MMCS system organization for these turbines is described. The architecture of distributed modular multimicroprocessor control system (MMCS) for turbo-unit technological process control is based on the modern concepts of modular multiprocessor systems with distributed architecture. The MMCS provides an integral computing entity with transparent multiprocessor organisation for application programs. The MMCS has a two-layer hierarchical system architecture. The upper layer implements the high-rate and low-rate control loop tasks, the regulation system diagnostics, automatic turbine startup, etc. The lower layer realises the local control and sensor functions and pre-processing in the distributed set of turbine points of control and measurement
