Steam turbine intelligent control integrated system for power plant and control method

Abstract

The invention discloses a steam turbine intelligent control integrated system for a power plant and a control method, and relates to the field of steam turbine intelligent control, the steam turbine intelligent control integrated system comprises a control machine and an operation table, the control machine comprises a data acquisition processing module, an automatic diagnosis module and a control module. The output end of the data acquisition processing module is in communication connection with the automatic diagnosis module, the output end of the automatic diagnosis module is in communication connection with the control module, the real-time storage unit is in communication connection with a cloud service memory, and the diagnosis storage unit is in communication connection with the cloud service memory. Data are uploaded to the cloud service memory through the real-time storage unit and the diagnosis storage unit for real-time storage, data loss caused by system abnormity is effectively prevented, a manual operation command is checked through a misoperation detection unit, when it is detected that the operation of the operation table is misoperation, a blocking unit sends a signal to a display module and a warning module to provide warning, so that the safety performance of manual operation is improved.

Description

technical field

[0001] The invention relates to the field of intelligent control of steam turbines, in particular to an integrated system and control method for intelligent control of steam turbines used in power plants. Background technique

[0002] Along with the pace of reform of the power system, under the background of the policy of "separation of factories and grids, bidding for grid access", the degree of reform is also constantly deepening. How to strengthen the operation and management of power generation, reduce the cost of power generation, and improve the competitiveness of enterprises in the market are new challenges for power generation enterprises. It is an effective way to realize online monitoring and real-time guidance for the economical operation of thermal power units. That is, according to the real-time operating parameters of the unit, the thermal economic index of the unit operation can be obtained online, and the operating conditions of the unit equip...
