Author/Source: Date: October 24, 2022. Click-through rate: 19. 1. Conditions for bidding: The name of this tender project is: Public tender for the Research and Application Demonstration Project of the PID Loop Tuning Optimization System at the Coal-to-Oil Branch of Ningxia Coal Industry Co., Ltd.* This project meets the bidding requirements, and public bidding for domestic qualification review is now being conducted for it. 2. Project Overview and Scope of Bidding 2.1 Project Overview, Scope of Bidding, and Division into Bid Sections/Packages: 2.1.1 Project Overview: In accordance with the requirements of the **Energy Group’s Guidelines for Intelligent Control and Intelligent Equipment Development in the Chemical Industry**, this project aims to carry out research on PID loop tuning optimization systems as well as demonstration applications. It involves monitoring the performance of approximately 5,500 control loops in the coal-to-oil production unit; PID tuning optimization will be applied to around 500 of these important control loops (not limited to just these 500). The operation status of PID systems will be monitored to address any decline in their performance caused by changes in operating conditions or valve wear, thereby preventing the need to switch from automatic mode to manual control. PID parameters will be optimized in real time. It is necessary to entrust a specialized agency to develop a PID loop tuning and optimization system based on the actual operating conditions of the coal-to-oil company, in order to increase the utilization rate of automatic control systems and the stability of the control loops, thereby achieving full automation across the entire process. 2.1.2 Scope of the tender: (1) Develop a PID loop tuning and optimization system suitable for the coal-to-oil subsidiary (the system shall receive free upgrades for life and be open in design: its functionality must not be affected by upgrades to the server operating system, platform software, or hardware; a commitment letter must be provided to ensure free lifetime upgrades for the PID loop tuning and optimization system), including the establishment of the system’s network architecture and the provision of OPC communication access for all 17 PID loops in the Emerson control systems ； (2) The PID loop tuning and optimization system needs to monitor, evaluate, and statistically analyze the performance of all control loops (approximately 5,500) in various units of the Coal-to-Liquid Branch. Additionally, it must tune the parameters of 500 critical control loops (these loops can be replaced according to the requirements of the tenderer). The system is expected to perform the following functions: ① Establish real-time communication with the DCS systems of each unit via the OPC-DA protocol, collect relevant operating data from the control loops, and store such data ； ②The PID performance evaluation system automatically collects the operational data of PID loops, and it dynamically calculates and monitors parameters such as the degree of automation and control stability of these loops in real time. It allows users to view the degree of automation and control stability for any unit or loop at any time point within one year after the project is implemented, on authorized computers; it also enables sorting and comparison of these values ； ③It features PID parameter self-tuning capability: the system automatically analyzes the process data of the PID loop, continuously updates the performance benchmarks in response to changes in dynamic characteristics, ensures the long-term effective operation of monitoring and diagnostic functions as well as real-time monitoring of controller performance, and provides appropriate PID parameter suggestions when the loop characteristics change, thereby achieving adaptability in loop control and keeping the controller in a high-performance operating state ； ④It is capable of evaluating and analyzing the operational performance of PID loops, assigning ratings such as excellent, good, medium, or poor. It enables rapid identification of performance issues within PID loops, and through graphical analysis methods, it provides a clear and intuitive overview of the factors affecting loop performance, along with evaluation recommendations ； ⑤Provides circuit performance metrics such as stability, accuracy, speed, smoothness, saturation level, control error analysis, oscillation index, non-linearity index, viscosity index, and valve stroke for controller circuits ； ⑥For circuits that require tuning, after tuning the attenuation ratio of the control circuit in automatic mode is between 4:1 and 10:1, with the maximum deviation not exceeding 2% of the range of the controlled variable; moreover, the automation utilization rate of the tuned circuits reaches 98% (except for those circuits that cannot be tuned due to objective reasons such as valves and instruments) ； ⑦The control loop performance evaluation software can identify faults such as valve stickiness, process disturbances, loop coupling, and distributed oscillations through evaluation, and provide suggestions for resolving these faults. (3) Responsible for the procurement, installation, deployment, system integration, and on-site commissioning of the PID loop tuning optimization system ； (4) Responsible for delivering documents related to the PID loop tuning and optimization system, as well as carrying out knowledge transfer and training activities ； (5) Provide all software and hardware required to implement this project and meet the requirements of Level 2 protection for industrial control networks ； (6) The bidder shall purchase personal accident insurance for its employees, with the compensation limit being at least the following amount: RMB 1 million per person in case of death or disability ； Medical expenses: 200,000 RMB per person ； (7) Based on the research findings of the project, publish 1 scientific and technical paper in a Chinese core journal or higher; file 2 patent applications (1 invention patent and 1 utility model patent); and apply for 1 software copyright ； The primary author of the paper, patent, and software copyright is a staff member of the tendering party, and the primary entity responsible for them is also the tendering party ； The paper must obtain acceptance proof from a journal before the project is approved, and the patent must enter the processing stage at the **Intellectual Property Office before the project is approved. (8) Responsible for assisting the tendering party in preparing project acceptance documents such as research project reports and work reports, as well as helping the tendering party with the evaluation of scientific and technological achievements and the submission of applications for awards for scientific and technological progress.
