2022In that year, our company implemented CNOOC Zhuhai Natural Gas Power Generation Co., LTD-The "Intelligent Safety Pre-Control System for Main and Auxiliary Machinery and Lubrication" project of Yihai Power Plant includes: Online monitoring, early warning and diagnosis system for main machine vibration status6kVAuxiliary machine vibration monitoring, early warning and diagnosis system380V Auxiliary machine vibration monitoring and early warning system, intelligent control system for main and auxiliary machine oil quality.

Project Introduction

1. The two sets of generating units of Zhuhai Electric Power total4This mainframe equipment is already equipped with dynamic data acquisition devices such as bearing vibration, acceleration, and differential expansion, and is fitted with Bentley3500Collection framework4Set. This project will start fromBently3500The system conducts data collection to achieve real-time monitoring of the operating status of the host equipment, early warning, intelligent fault analysis and diagnosis, and other functions.

2. The important auxiliary equipment of the two sets of units of Zhuhai Electric Power includes high-pressure feed water pumps, medium-pressure feed water pumps, etc20Taiwan6kVAuxiliary machine. Install acceleration sensors on the above-mentioned important auxiliary machines, and transmit the vibration data to the auxiliary machine vibration state monitoring, early warning and diagnosis system through data acquisition devices and transmission devices, to achieve real-time monitoring, early warning, fault analysis and diagnosis of the auxiliary machine's operating status and other functions.

3. Two sets of units of Zhuhai Electric Power are equipped with vacuum pumpsEHOil pumps, lubricating oil pumps, gas turbine casing fans, desalination water pumps, etc68Taiwan380VAuxiliary machine. This project will install wireless vibration sensors on the above-mentioned important auxiliary machines and transmit the vibration data to the auxiliary machine vibration status monitoring, early warning and diagnosis system through wireless transmission to achieve the purpose of monitoring380Functions such as online inspection, early warning and diagnosis of auxiliary machines.

Implementation effect

1. The "Online Monitoring, Early Warning and Diagnosis System for Mainframe Vibration State" provided by BKC, a visual intelligent safety pre-control system for steam turbine generator sets, is essentially a set of "intelligent visualization"TDMIt is equipped with fault type models of mainstream steam turbine manufacturers, expert logical experience models, event reasoning algorithms and big dataAIAlgorithms, etc., can automatically assess the safety status of the unit, intelligently warn of the causes of abnormalities and push operation and maintenance suggestions, and can detect shaft system abnormalities in advance to prevent the deterioration of faults and damage to equipment. After the unit trips, the cause of the trip can be quickly identified, shortening the time for accident handling.

2. "6kVThe auxiliary machine vibration Monitoring, early Warning and diagnosis system can display the health status and reliability of the equipment, provide accurate and reliable data basis, automatically give analysis and diagnosis conclusions, automatically push the location, level, cause and solution of equipment faults, reduce the input of vibration analysis personnel, and promote the vibration monitoring work to be more procedural and standardized. Assist equipment management engineers in making scientific maintenance plan decisions;

3. "380V The auxiliary machine vibration monitoring and early warning system, an intelligent safety pre-control system for auxiliary machines, is equipped with built-in fault type models, expert logic experience models, event reasoning algorithms, and big dataAIAlgorithms, etc., can automatically assess the safety status of equipment, intelligently warn of abnormal causes and push operation and maintenance suggestions, which can detect equipment abnormalities in advance and prevent faults from worsening and damaging the equipment.

4. The online monitoring technology for lubricating oil of key unit equipment in the "Intelligent Control System for Main and Auxiliary Engine Oil Quality" can enhance the lubrication safety monitoring of equipment and establish it on the basis of scientific management. It is of extremely significant importance for ensuring balanced production of the equipment, maintaining its integrity and giving full play to its efficiency, improving lubrication conditions, reducing equipment failures, and enhancing the economic benefits of enterprises and society.
