Application of the information from Hydropower Dispatch Automation System in the forewarning and control of the power system

Hydropower Dispatching Automation System (HDAS) has played a significant role in the online monitoring, hydropower dispatching and accidents precaution. This paper proposed a method for the advanced application of HDAS. Emphasis is placed on the algorithms for accident precaution and assistant decision-making, taking advantage of the information provided by HDAS and D5000. The algorithms proposed in this paper are also applied to develop a dispatch software package, which is employed in the dispatching automation system in Sichuan Power Grid. An example of the online application is used to verify the effectiveness of the methods.
