The content of the investigation and research includes integrated automation systems for large-scale hydropower stations,automation control systems for cascade centralized control centers and automation dispatch systems for large-scale water diversion engineering projects.

Problems likely to be encountered in the process of centralized control center establishing are analyzed.

The general policies to construct the mutual fault-tolerant and standby SCADA(supervisory control and data acquisition)system based on multi-agent technology for multi-area centralized control centers are presented in the paper in order to raise the safety and operational reliability of the power grid without additional equipment investment.

This paper introduces the key elements of the control system for the Dadu River cascade hydropower stations centralized control center,such as the network structure of the control system,approach for data exchange and reliability design of communication between the control center and the cascade hydropower stations,and the centralized control strategy.

This paper introduces the process, technical scheme and characteristics of the synthetic automation reconstruction project of the 220 kV Taihe Substation and its control center.

In order to enhance the transmission efficiency and lowering the power-waste,the system used a network scheduling mechanism based on center controlled virtual token of intermittent working.

Though the situation of the staff shortage in the substation and problems about operation management of the attended substation,this paper introduces a centralized control management program which establishes the center of the centralized monitor to control the whole region,and sets up operating staff by each substation location to perform the operation management on spot.
