4 FAQs about The role of DC inverter in substation
How does an inverter substation work?
The inverter substation sends power to the main grid by regulating the DC voltage of the third rail. During deceleration, regenerative braking energy is injected to the third rail and if there is no other load to absorb it, the voltage of the third will increase.
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.
How does a DC inverter work?
The inverter first receives DC power from your source (battery, solar panel, or DC power supply). Input filters smooth out any voltage fluctuations and protect internal components. Powerful semiconductor switches (typically MOSFETs or IGBTs) rapidly turn the DC current on and off thousands of times per second. This creates a series of DC pulses.
