What is an inverter substation?
Inverter substations are designed mainly to maximize the use of braking energy by returning the surplus to the alternating current (AC) electrical grid. Inverter substation projects must provide conditions to minimize the level of harmonics, in order to guarantee a good quality of energy that returns to the AC grid.
Does inverter substation reduce energy consumption?
The results of the study of Line 1 - Blue of the São Paulo’s metro city indicate that using inverter substation could reduce the energy consumption at the rectifier substation (RSS) by nearly 12,94% compared to the system without the inverter substation. 1. Introduction
Can an inverter substation be used without a catenary?
However, inverter substations do not allow operation without the catenary or third rail and cannot be used to stabilize voltage or reduce peak power. The use of inverter substations makes it possible to recover energy from braking at any time, since the AC medium voltage network are permanently receptive.
Can an inverter substation regenerate train braking energy?
