Abstract

A method of quickly analyzing the topology of a large grid based on Graphx comprises the following steps: building a power data analysis platform based on Spark; acquiring a grid model of a smart grid scheduling control system; hierarchically partitioning the grid model according to regions, power plants and transformer substations, and mapping the grid model to a Graphx database in the form of object; acquiring the switch / breaker status of the smart grid scheduling control system; and making a distributed topology analysis of a power network to form a power network topology relationship, and visualizing the power network topology relationship. According to the invention, a standard and high-availability power system topology analysis cloud platform is built, the data processing ability and topology analysis ability are improved, and the demand of advanced application of a smart grid for grid topology analysis is satisfied.

Description

technical field [0001] The invention relates to the technical field of design of power network topology logic diagrams, in particular to a Graphx-based fast topology analysis method for large power grids. Background technique [0002] With the rapid development of smart grid and the expansion of power network scale, the operation mode of power grid has become more and more complex. Coupled with the influence of factors such as inter-regional interconnection, the construction of power system and large-scale operation system requires efficient and accurate integration. The high-efficiency model is the guarantee of this technology. Therefore, it is particularly important to establish a standard and open power system topology analysis platform to promote the interoperability between applications, reduce production and maintenance costs, and improve the real-time performance of the system. [0003] The International Electrotechnical Commission (IEC) has formulated some standards...
