Abstract

The invention relates to the technical field of urban rail transit, in particular to a calculation method for load power of urban rail transit. The load power of the rail transit is a sum of total complex power of a traction station, total power of a voltage reduction station, reactive loss of a main substation transformer and charging power of a cable; and a load of the rail transit can be obtained by calculating the total complex power of the traction station, the total power of the voltage reduction station, the reactive loss of the main substation transformer and the charging power of thecable. The invention discloses the calculation method for the load power of the urban rail transit. By calculating the load power of the urban rail transit, the electric energy quality operation levelof the urban rail transit can be comprehensively known, so that the electric energy quality emission and transmission characteristics of the load of the rail transit can be accurately grasped, the power grid access modeling simulation and test assessment technology research on the load of the urban rail transit is carried out, and technical support and quantitative standards are provided for guaranteeing safe power supply and operation of the load of the urban rail transit.

Description

technical field

[0001] The invention relates to the technical field of urban rail transit, in particular to a method for calculating load power of urban rail transit. Background technique

[0002] With the continuous expansion of my country's cities and the rapid development of economic construction, the urbanization process is gradually accelerating, the urban population has increased sharply, the traffic demand has increased sharply, and the contradiction between urban traffic supply and demand has become increasingly tense. Become a "bottleneck" problem that restricts urban development. Urban rail transit has become an effective way to solve traffic congestion problems in large and medium-sized cities in my country by virtue of its characteristics of fast, convenient, safe, large transportation volume and high transportation efficiency. According to the "Urban Rail Transit 2016 Statistics and Analysis Report" issued by the China Urban Rail Transit Association, as of the e...
