Large Thermal Power Plant Monitoring Information System (sis) Design And Implementation

The power industry is the leading basis industries of the national economic and occupies an extremely important position in the national economy. In 2002, China's electric power system has been reformed as the core content of "separating of government and enterprise, factory and grid, bidding of power generation fields ", introducing competition, breaking up monopolies and establishing a new market mechanism. With the further deepening reform, how to increase their own efficiency of power enterprise, and enhance market competitiveness is a major problem to generation enterprises.Power system is a huge input and output of energy conversion system. In order to improve the efficiency of power generation, optimizing production operation is an extremely important work. Generation enterprises are as objects to study in this paper, according to the operating characteristics of plant's actual production and demands of optimizing production management, on the basis of explaining SIS background and development, in-depth discussing the composition, functions, networking and database technology of SIS. From application it discussed SIS position in information system of plant, use objects, and function in production management and optimizing operation. In SIS network, this paper in detail described the network needs analysis, network design principle, network architecture, etc.; in regards of SIS real-time / historical database, it in detail described the functional requirements of the database, data compression principle, real-time / historical database iHistorian and typical configuration. Combine with SIS system features of Lanxi power plant with 4 x 600 MW supercritical coal-fired units' projects, it layout detailed implementation projects and functional descriptions. Database operating under the premise of large date and the second security protection system have been detailed analyzed. Designs have secure and reliable network architectures and advanced practical applications.Layout and design in this paper have been adopted and implemented by Lanxi power plant.
