    摘要: A digital arrangement for controlling a gas or steam turbine in which operating parameters of the turbine are sensed at a regular rate. Control parameters are then calculated from the operating parameters by at least one control and regulating program with predetermined reference values. The turbine is controlled and monitored in operation, in accordance with the calculated control parameters for the purpose of safeguarding against excess speed or surging. At least two computer systems are operated in parallel and at different speeds, and communications prevail between these two computer systems. The first of the computer systems is operated at a substantially rapid rate and with a limited supply of commands, together with an individual control and regulating program having a set of reference values. The second computer system is operated at a slower rate than the first computer system and with a greater supply of commands. The second computer system is operated with a plurality of control and regulating approaches and sets of reference values. Predetermined operating parameters are acquired by the first computer system for calculating control parameters and transmitting the calculated control parameters to the turbine. A new control and regulating program is selected by the second computer system when operation of the turbine is changed.
