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.
