The plant-level real time information system of the Tianhuangping Pumped Storage Power Plant concretizes the data from 5 monitoring and control subsystems, and forms 2 long time history databases, one storing 30 000 tags with at least 1 s resolution, and another storing all events from the operator stations of the distributed control system.

Design and Implementation of Data Middleware in the Real Time Information System;

The paper presents analysis and discussion of the hard ware allocation and the function of the soft ware of a preliminary designed real time information system for a certain power plant, which may serve as a reference for the ultimate decision on the engineering project.

This paper introduces the system structure and work principle of the upgraded real time information system in Wangting Power Plant, and then expounds the realization way and function features of this system on B/S computing mode.

Production real-time information system is the production management technology and the real-time information system for workshop tier.

Advancing the application of load distribution optimization in SIS;

Application of Agent Technology in SIS;

The key points to be concerned in SIS planning and construction were pointed out as the following three aspects: real-time historian, advanced applications and system security.
