Regulation system for a steam turbine installation |
摘要 |
A regulation system for a steam turbine installation comprising a steam generator and a multi-stage turbine installation incorporating a high-pressure stage. The regulation system comprises a regulation valve arranged between the steam generator and the high-pressure stage of the turbine installation and a by-pass valve connected in parallel with said high-pressure stage, as well as control devices with associated control circuits for said valves. The control device for the by-pass valve is influenced by the signal from the control circuit of the regulation valve such that when the opening of the regulation valve exceeds a predetermined magnitude the control device for the by-pass valve opens such by-pass valve to a predetermined magnitude. Further, the control circuit of the by-pass valve is connected in parallel with a differentiation element which influences the degree of opening of the by-pass valve as a function of variations in the signal received from the control circuit of the regulation valve.
