SRE POWER proposed the design scheme of HVDC power carrier intelligent dimming system, focusing on forward-looking design. Advanced lighting technology effectively realizes high efficiency, cost reduction and energy saving of enterprises, and simultaneously reduces installation and maintenance costs. At the same time, it makes the lighting fixtures reasonably scientific and efficient management through the centralized control of the monitoring center. This efficient, professional and high-quality service provides customers with overall lighting solutions.
Dimming System Solutions
There are various disadvantages of using alternating current in
engineering lighting applications, such as large AC line loss, easy to leakage
and electric shock accidents. The advantages of HVDC power supply are
highlighted, as the DC bus is isolated from the ground, which significantly
improves the safety of the system. In addition, DC transmission losses are
small, generating reactive power, while it saves cables and reduces
installation costs.
In terms of lighting control, the method of using power lines to transmit broadband carrier signals eliminates the dimming light in traditional dimming control applications, significantly saves material costs and reduces wiring difficulty in projects.
The HVDC power supply module is used to power the entire system; the broadband carrier communication module is used for lighting system control. Compared with existing technologies, it improves electricity safety and improves electricity efficiency. It removes dimming light by transmitting control signals through power lines and reduces installation and maintenance costs. At the same time, it enables reasonable, scientific and efficient management of lighting fixtures according to different scenarios and time points through centralized control of the monitoring center.
