Embodiment 1

[0028] figure 1It is a schematic structural diagram of an open architecture condition-based maintenance system for a power plant according to an embodiment of the present invention, including: a data collection layer 11, a data operation layer 12, a state detection layer 13, a health evaluation layer 14, a prediction evaluation layer 15, and suggestion generation Layer 16. Wherein, each of the layers uniformly adopts the Open Architecture State-Based Maintenance (OSA-CBM) specification, so as to realize the interchangeability of products from different manufacturers with the same function in each layer. The functions and interrelationships of each layer can be specifically expressed as follows:

[0029] Data Acquisition Layer 11 (Data Acquisition Layer) is used to collect field data of power generation equipment in power plants. Specifically, sensors, smart instruments, and field buses (such as profibus, FF, CAN, etc.) can be used to connect to the site for data collection. ...

Embodiment 2

[0053] figure 2 Shown is a schematic structural diagram of an open architecture condition-based maintenance system for another power plant proposed by the present invention, which includes a data acquisition layer 11, a data operation layer 12, a state detection layer 13, a health evaluation layer 14, a prediction evaluation layer 15 and suggestion generation Layer 16 is similar to that described above, so it will not be repeated here. The system also includes an external interface module 21 and an information expression module 22, specifically described as follows:

[0054] The external interface module 21 (IO) is used to realize the communication between various layers of the system and between the system and the outside. Specifically, the open architecture condition maintenance system of the power plant acquires the operating data of the power plant and its electrical system through real-time interfaces such as OPC, RS485, and IEC61850; uses JSON table structure or Comtra...

Embodiment 3

[0057] image 3 It is a schematic flow chart of a design method of an open architecture condition-based maintenance system of a power plant according to an embodiment of the present invention, including: step S31, establishing a data collection layer for collecting field data of power plant power generation equipment; step S32, establishing a data operation Layer, used to extract the characteristic value of the field data; step S33, establish a state detection layer, used to receive the field data and characteristic value, and compare with the preset threshold value to obtain the state detection value; step S34, establish a health The evaluation layer is used to judge the current health state of the power generation equipment based on the state detection value; step S35, establishing a prediction evaluation layer, which is used to predict the future health state and remaining service life of the power generation device based on the current health state; step S36, A suggestion ...

Abstract

The invention provides an open system architecture state maintenance system and method of a power plant, a medium and a terminal, which are used for solving the technical problems of single function,high price and incompatibility of a power plant state maintenance product in the prior art. The system comprises: a data acquisition layer which is used for acquiring field data of power generation equipment of a power plant; a data operation layer which is used for extracting characteristic values of the field data; a state detection layer which is used for receiving the field data and the characteristic value and comparing the field data and the characteristic value with a preset threshold value to obtain a state detection value; a health evaluation layer which is used for judging the current health state of the power generation equipment based on the state detection value; a prediction evaluation layer which is used for predicting the future health state and the remaining service life of the power generation equipment based on the current health state; and a suggestion generation layer which is used for generating a power generation equipment maintenance suggestion based on the current health state, the future health state and the remaining service life.

Description

technical field [0001] The invention relates to the technical field of maintenance of power plants, in particular to an open architecture condition maintenance system, method, medium and terminal of a power plant. Background technique [0002] In the context of a high proportion of renewable energy consumption, the participation of thermal power units in deep peak regulation often leads to greater equipment wear and life loss, as well as higher maintenance costs per installed unit, and also threatens the operational safety of coal-fired units and reliability. Thermal power enterprises urgently need to adopt condition-based maintenance technology, hoping to achieve obvious results in improving the health of equipment and reducing maintenance costs per kilowatt, and improving the competitiveness of enterprises in the continuously liberalized power market. [0003] At present, some domestic experts, scholars and researchers have made some explorations on the concept, structure...
