The invention provides a power transmission network power transmission capacity evaluation system based on a big data platform, and relates to the field of power transmission network power transmission capacities. A merging unit (1) merges and integrates data acquisition and finally feeds back the data to an information substation network switch (5). A monitoring IED (3) plays a role in monitoringthe control IED (2). A protection IED (4) plays a role in protecting the control IED (2), and a data layer communication network (6) receives external meteorological information in real time througha satellite (10) and feeds back line information data and real-time weather data of the information substation network switch (5) to the control center switch (7). A control center switch (7) transmits all information data to a server (9) and a man-machine interface (8) of the Hadoop cluster system with three built nodes, the server (9) performs quick data processing, and the man-machine interface(8) performs information input / output.
Description
technical field [0001] The invention relates to the field of power transmission capacity of a transmission network, in particular to Hadoop big data analysis and processing. Background technique [0002] In recent years, large-capacity, ultra-large-scale, ultra-high voltage, AC-DC hybrid, informatization, flexibility, and marketization are the most prominent signs of modern power systems. With the rapid growth of diversified power loads, the widespread application of high-density and high-penetration distributed power sources, and the centralized grid connection of large-scale fluctuating energy sources, the network loss increases and the stability of the power system is getting lower and lower. Therefore, in combination with the current national support for flexible AC transmission technology and UHV transmission technology, the transmission capacity of the transmission network is evaluated and analyzed through the big data platform, starting from the reasons for the limite...
