A Practical Approach to Generating Trend Data of Power Grid Operation for Pre-dispatching System

Pre-dispatching of power automation system can quickly and accurately simulate the operation of power grid in the future and evaluate by means of analysis. It provides technical support for dispatcher's actual operation. When there are significant changes or emergencies, pre-dispatching can be triggered. This enables dispatchers to grasp the operational risks of power grid ahead of time. In such a process, the trend data of power grid operation is the foundation of pre-dispatching. In this paper, a practical method of trend data generation is proposed based on real-time data, planning and forecasting data, combined with risk analysis and early warning function services. It can provide continuous running data for the nucleus calculation module of pre-dispatching. A basic data environment for pre-dispatching is constructed.
