Embodiment 1

[0059] This embodiment provides a diagnostic control method based on data association of the main valve opening of the water turbine. This method is applied to various automatic control systems. According to the actual change of process data, when a certain device that generates process data is abnormal, The main valve of the turbine reports an error instead of shutting down to avoid the impact of the overall shutdown.

[0060] Specifically, such as figure 1 As shown, the method includes a data association establishment step S1 and a data association processing step S2. The step of establishing data association includes the following sub-steps:

[0061] S11: Establish an association relationship of data, the data includes one control data and at least one non-control data; the control data is the opening degree, and the non-control data is other data associated with the opening degree, including the main valve One or more of opening / closing speed, servomotor oil pressure, se...

Embodiment 2

[0111] This embodiment provides a diagnostic control system based on data association of the main valve opening of the water turbine. The inventive concept of this system is the same as that of Embodiment 1. When the process data equipment is abnormal, an error is reported to the main valve of the turbine instead of shutting down, so as to avoid the impact caused by the overall shutdown.

[0112] Specifically, such as figure 2 As shown, the system includes an opening data association establishment module and an opening data association processing module, and the opening data association establishment module includes:

[0113] Data association unit: used to establish an association relationship of data, the data includes one piece of control data and at least one piece of non-control data; the control data is the degree of opening, and the non-control data is other data associated with the degree of opening , including one or more of main valve opening / closing speed, servomot...

Embodiment 3

[0131] Based on the realization of Embodiment 1, this embodiment also provides a storage medium on which computer instructions are stored, and when the computer instructions are run, the diagnostic control method based on the data association of the main valve opening of the hydraulic turbine described in Embodiment 1 is executed. A step of.

[0132] Based on this understanding, the technical solution of this embodiment is essentially or the part that contributes to the prior art or the part of the technical solution can be embodied in the form of a software product, and the computer software product is stored in a storage medium. Several instructions are included to make a computer device (which may be a personal computer, server, or network device, etc.) execute all or part of the steps of the method described in each embodiment of the present invention. The aforementioned storage medium includes: U disk, mobile hard disk, read-only memory (Read-OnlyMemory, ROM), random-acce...

Abstract

The invention discloses a diagnosis control method and system based on water turbine main valve opening degree data association, a storage medium and a terminal, the method comprises an opening degree data association establishment step and an opening degree data association processing step, and the data comprises control data and non-control data; the control data is the main valve opening degree; the non-control data comprises one or more of main valve opening / closing speed, a servomotor oil pressure, a servomotor stroke, the main valve opening / closing time, the motor current and the motor voltage; the method comprises the steps that the incidence relation between the opening degree and non-control data is established, the data collected in real time are judged, and when the multiple pieces of non-control data do not fall into the limit interval of the value corresponding to the opening degree data, the opening degree data are diagnosed and errors are reported. AOnly data is subjected to correlation diagnosis and then control is carried out, so that control failures caused by faults or defects of a sensor and a control system can be effectively avoided.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a diagnosis control method, system, storage medium and terminal based on data association of the opening degree of a hydraulic turbine main valve. Background technique [0002] The control object is also called the controlled object. In the automatic control system, it generally refers to the controlled equipment or process as the object, such as the control of reactors and rectification equipment, or the control of heat transfer process and combustion process, etc. From the perspective of quantitative analysis and design, the control object is only a part of the factors affecting the input and output parameters of the controlled equipment or process, not all of the equipment. In the automatic control system, as a generalized control object, actuators (regulating valves) and measuring and transmitting devices other than controllers (regulators) are included. As a control object...
