Use of simulation for development of process control system

The use of simulation at different stages of life cycle of process control system is described. The application of this approach to the development of distributed process control system of North-Muisk railway tunnel (Baikal-Amur Railroad, East Siberia, Russia) is considered. The development of distributed process control system was carried out with the help of a simulator. The simulator contains the following programs and models: an operator interface, control programs, a model of processing equipment, a model of railway traffic, a model of the outside world, and a model of microclimate inside the tunnel. The simulator was used for following purposes: debugging of control programs in test bed, optimization in test bed, training of operating personnel, and testing of control programs in real-world system. The models were executed within the framework of distributed simulation system Mera. Mera is the C++ based process-oriented discrete simulation system. There are various implementations of the simulation system Mera. The sequential implementations are realized for Windows and in Java. The distributed implementations are realized for Supercomputer MBC 1000/M (Russia). A new implementation of the simulation system Mera in Java - transportation simulation system also is described.

Simulation of Performance of the Longwall in Underground Coal Mine

A simulation model of the performance of the longwall in underground coal mine is presented. The simulation model is developed with the help of our own simulation system MTSS, which contains a specialized library of mining equipment models and a coal seam model. The main goal of the simulation for coal mining technological processes in stoping face is the evaluation of productivity of a cutter-loader depending on different factors. Such factors are: technical parameters of a cutter-loader, size of a longwall face, conditions and constrains of technological processes in stoping face, geophysical state of a coal seam.

Simulation of Technological Processes in Coal Mining

Abstract This paper describes the new visual interactive simulation system of technological processes intended for the development and execution of simulation and emulation models for process control systems. A set of simulation models was developed with the help of this simulation system. These models were developed with the goal to be used as a quality assurance tool for new process control systems of coal mining. Simulation models of various subsystems of coal mining were united to create simulation environment of coal mining. Simulation environment is visually interactive, include emulation models of technological equipment and allow to simulate complex situations in mines and working faces visually as well as to check the response of process control system developed for these situations. Simulation environment was used for testing of algorithms of programmable logic controllers as a part of process control systems prior to commissioning. Simulation environment can be used not only for existing coal mining techniques but also for perspective (robotized) techniques.
