摘要
分散控制系统(DCS)是火电机组的“神经中枢”,但其核心软硬件自主化率较低,对外依存度较高。在分析DCS应用及国产化现状基础上,介绍了国内首套全国产DCS—华能睿渥DCS的设计、开发与应用情况。针对缺少国产专用芯片、模拟量芯片功能不全、软硬件适配性差等问题,设计了以国产CPU+FPGA为核心的主协计算框架,研发了基于国产ADC、DAC芯片的自校准补偿方法,提出了国产MCU与FPGA芯片软硬件协同的现场总线通信技术,研制出全国产冗余控制器及I/O模件,并大幅提高模拟量卡件精度,同时实现了现场总线技术国产化。经国家权威第三方测试,该国产控制系统的功能与性能达到或超过国家和行业标准要求;经300 MW及1 000 MW等级机组示范应用表明,该控制系统完全满足大型火力发电厂应用要求,标志着我国火电机组核心控制设备实现完全自主可控。
The distributed control system(DCS) is the “nerve center” of thermal power unit, but its core software and hardware have a lower localization rate and a higher degree of dependence on foreign countries. In this review,after analyzing the current status of DCS application and localization, the authors outline the design, development and application of the first set of nationally produced DCS in China, namely the “Huaneng Revival” DCS. Aiming at solving the problems of lack of domestic dedicated chips, incomplete functions of analog chips, poor software and hardware adaptability, a main collaborative computing framework with domestic CPU+FPGA as the core is designed, and self-calibration compensation methods based on domestic ADC and DAC chips are developed.Moreover, the software and hardware cooperative fieldbus communication technology based on domestic MCU and FPGA chip is proposed. As a result, fully domestic redundant controllers and I/O modules are developed, with the accuracy of analog modules greatly improved, and the localization of fieldbus technology is realized. The thirdparty test shows the function and performance of the domestic control system meet or exceed the requirements of national and industry standards. The demonstration application of 300 MW and 1 000 MW units shows the research results fully meet the application requirements of large-scale thermal power plants, indicating that China has completely autonomously controlled the production of core control equipment in the power generation field.
