Abstract

The invention discloses a control method for an unattended turbine, and the control method is applied to an automatic turbine control system. The control system constantly runs in the electrification state and has two basic control states including that firstly, when the turbine runs, the control system is in the running control state; and secondly, when the turbine stops running, the control system is in the standby state. By the adoption of the above technical scheme, the control method is applied to a turbine set with the hardware requirements for an automatic valve execution mechanism, an automatic grid connection device, an automatic water repelling device and the like, and under the condition of unattended operation, the functions of turbine starting, stopping, running, fault alarming, fault treatment and the like are achieved. Different from an existing turbine control system, control over running of the turbine set adopting the control system through workers is completely not needed after installing and debugging are finished.

Description

technical field [0001] The invention belongs to the technical field of power mechanical equipment, and relates to the control technology of steam turbines. More specifically, the present invention relates to a control method of an unattended steam turbine. Background technique [0002] The traditional steam turbine control system, whether it adopts PID or DCS system, requires operators to participate in the control, and the cost of steam turbine operators is relatively high. Contents of the invention [0003] The invention provides a control method for an unattended steam turbine, the purpose of which is to realize the automatic control of the steam turbine under unattended conditions. [0004] In order to achieve the above object, the technical scheme that the present invention takes is: [0005] The control method of the unattended steam turbine of the present invention is applied to the automatic control system of the steam turbine. The control system operates continu...
