Improvement of Process Closed-Loop Control Systems for Power Units

摘要

We describe the results of activities carried out at ZAO Interavtomalika (Interautomatika AG) on the development and putting into use of improved systems for closed-loop control of the main process values of Russian power units equipped with once-through boilers. We also consider a general approach for improving control systems and describe specific technical solutions taken for furnishing the main technological items of coal- and gas-and-oil-fired power units with closed-loop control systems.
