Problems solved by technology

The data acquisition systems of most subways only realize the basic data measurement function, but do not realize the analysis of the energy-saving effect of the system data, or based on the experience of experts, they propose non-uniform energy-saving effect evaluation indicators, resulting in the conclusion of energy-saving effect evaluation in various places. Realize unification; or only count the feedback power of each device, but do not analyze it from the perspective of the entire subway line, so the statistical results cannot truly reflect the energy-saving effect of the line

Embodiment

[0067] Take a subway line as an example. The energy consumption statistics of the reference system and the comparison system are shown in Table 1.

[0068] Table 1 Energy Consumption of Reference System and Control System

[0069]

[0070] It can be seen from the above table that among the four preset EFS operating voltages V of 1700V, 1710V, 1720V, and 1730V, 1700V should be selected as the EFS operating voltage V for this subway line. At this time, the system-level traction energy saving energy WES is the largest, which is 5987kWh, the system-level traction energy consumption energy saving rate ξ is the highest, which is 8.94%.

Abstract

The invention discloses a subway energy-saving monitoring system and a subway energy-saving effect evaluation method. The subway energy-saving monitoring system comprises an energy-saving index evaluation center CC, a main substation energy consumption monitoring unit MSU and a traction step-down substation energy consumption monitoring unit TSU. A main substation energy consumption monitoring unit MSU monitors data of a main transformer MT, a traction step-down station energy consumption monitoring unit TSU monitors data of a rectifier unit REC and an inversion feedback device EFS, then the data are uploaded to an energy-saving index evaluation center CC through a transmission channel, and the energy-saving index evaluation center CC stores the data and calculates an energy-saving effect evaluation index; the control instruction is issued to the inversion feedback device EFS; and the inversion feedback device EFS realizes device starting and stopping or starting of working voltage according to the requirement of the control instruction. The subway energy consumption data can be monitored, the inversion feedback device in the subway can be remotely controlled, the energy-saving effect of the system can be truly reflected and adjusted, and therefore system-level energy saving is achieved.

Description

technical field [0001] The invention belongs to the technical field of subway energy consumption regulation, and in particular relates to a subway energy-saving monitoring system and a method for evaluating subway energy-saving effects. Background technique [0002] Urban rail transit is a large power consumer with high energy consumption. Under the premise that energy conservation and emission reduction has become a major trend in the entire industry, energy conservation and emission reduction work for subways is imperative. [0003] The concept of the energy consumption monitoring system is to collect the electric energy load data of each subway system under the condition that the existing operation system remains unchanged, and to conduct statistics and analysis on the relevant electric energy load data. However, the data collection systems of subways in various cities still exist some problems. The data acquisition systems of most subways only realize the basic data mea...
