火电企业供热生产集中化、智能化的改造实践

摘要/Abstract

摘要：

望电公司在拓展热用户的进程中，先后进行供热一期、二期、三期改造，覆盖无锡市、苏州市多数地区。供热改造过程中，供热调度调节分散，缺乏统一调度。随着“智能供热”理念的兴起，望电公司启动热源集中化、智能化改造，将分散的机组侧供热控制进行一体化改造，建设具备集中控制能力的供热负荷调度中心，通过与热网及终端用户的数据对接，实现了热网的热源侧自动调整，在国内工业供热领域具有领先水平及示范意义。针对全厂复杂的供热系统及运行方式，通过数据的实时分析处理，建立热力系统性能分析模型，得出供热抽汽成本在线计算数据，结合基于分时控制的多个调节回路对同一目标参数的协同控制，精准实现了供热闭环优化控制，具备朴素的智慧供热理念。

Abstract:

Wangting Power Generation Company (hereinafter referred to as Wangdian company)has successively carried out the first, second and third phase transformation to meet the increasing heating demand in major area of Wuxi and Suzhou.During the transformation, the heat supply dispatching was scattered and lacking of unified dispatching command. With the rise of the concept of “intelligent heating”, Wangdian company setup a centralizing and intelligent transformation on heating supply which integrated the decentralized heating control on unit side, and built a heating load dispatching center that was capable of centralizing control. The network automatic adjustment on heating supply side was realized by connecting the data from terminal users to that from supply side. The transformation was of leading and demonstration significance for domestic heating industry. Considering the complex operation mode of the whole power plant, the performance analysis model of the heating system was established and the steam extraction cost for heating supply was calculated online by realtime data analysis and processing. Coordinated control made by timesharing controlled multiple regulating circuits on a single targeted parameter realized closedloop optimization control on heating accurately,which represents a control concept of simplicity and intelligence.
