[Abstract]:With the development of China's modernization process, the revolution of electric power technology is accompanied by the reform of modern electric power system. Power dispatching automation is also the need of grid development and one of the technical support of electric power to the market. In this environment, the power grid technology is developing rapidly and maturely, the intelligent level of the power dispatching master station system is becoming higher and higher, the intelligent technology emerges in endlessly, the dispatching automation and the substation digitization system are continuously updated. This paper takes this opportunity to take the domestic advanced power dispatching technical support system as the content, and takes the construction of Xinxiang smart grid electric power dispatching technical support system (D5000) as the realistic background in the parallel transition period. This paper makes some practical research and discussion on the technology of the current power dispatching master station system, in order to provide some constructive development directions and feasible implementation schemes for the future work related to the intelligent power grid dispatching in the region. The main work is as follows: it is necessary to establish a perfect integrated provincial-land network model for the new intelligent power grid dispatching automation system. Compared with the original hierarchical scheduling automation model, the integrated model has obvious advantages in intelligence. From the aspects of hardware and software configuration, operation mode, master station requirement, dispatching communication function upgrade and so on, the new scheduling master station system is more intelligent. In view of the practical problems in the construction period of the new dispatching master station D5000 system, this paper analyzes and summarizes a series of typical experiences in the parallel transition period, and puts forward how to improve the security of the new system construction and speed up the debugging efficiency of the new system. The core of all intelligent advanced applications of D5000 system is the state estimation function, which is also the main assessment index in the smart grid integration model. This paper studies the state estimation on the premise of realizing the function of D5000 system, and analyzes and summarizes the experience and method of improving the qualified rate of the model state estimation in Xinxiang area. The large span of voltage automatic control function in D5000 system is an obvious index to improve the intelligent level of dispatching and monitoring personnel. The automatic control function of voltage, the practical problems and unexpected situations that need to be solved in the process of construction and realization are the directions of this paper. It is hoped that through the analysis of this aspect, it will help the city level control center to carry out the control work of bus voltage crossing line more effectively.
