Embodiment 1

[0032] In steps S2-S4, when calculating the energy within the sampling period, when the collection point is located on a train motor car and the current is positive, the energy is traction energy consumption; when the collection point is located on a train motor car and the current is negative, the energy is regenerative braking energy; When the collection point is a train trailer, the energy is auxiliary energy consumption, and the overflow thresholds of traction energy consumption, regenerative braking energy, and auxiliary energy consumption are set separately β 1 , β 2 and beta 3 , the energy values ​​of different categories are accumulated in multiple cycles to get 0 to W 1 , W 2 and W 3 , when the energy accumulation value of a certain category exceeds its corresponding energy overflow threshold, the module will give a pulse indicating the energy overflow of this category, and clear the accumulated energy of this category to re-accumulate the energy of this category, ...

Abstract

The invention discloses a train operation energy consumption metering method, which comprises the following steps of: S1, acquiring voltage and current in a train operation process by adopting a voltage sensor and a current sensor, S2, multiplying the voltage and the current by a signal gain item to obtain original voltage and current, and in a sampling period, calculating real-time power according to the original voltage and the current value, and integrating time to obtain an energy value in the sampling period. According to the invention, the train traction energy consumption, regenerative braking energy and auxiliary energy consumption can be accurately metered and stored in real time, a rail transit operation company can conveniently manage energy data, accurate data support is provided for train operation energy analysis, and a foundation is laid for energy conservation and emission reduction of urban rail transit.

Description

technical field [0001] The invention belongs to the field of energy measurement, in particular to a method for measuring energy consumption in train operation. Background technique [0002] As my country's urban population grows year by year, more and more cities include urban rail transit construction in their development plans. However, the rapid development of urban rail transit will inevitably bring about huge energy consumption, because the development of green rail transit has attracted more and more attention. To achieve energy-saving urban rail transit energy saving and emission reduction, it is first necessary to accurately measure the energy of the train. The energy consumption in the process mainly includes traction energy consumption and auxiliary energy consumption, in addition, regenerative braking energy will also be generated; [0003] There are certain deficiencies in the existing energy consumption measurement methods for train operation. It cannot measure...
