DC Power Transmission and Communication to DC Loads

active, Most Current
Organization: IEEE
Publication Date: 9 November 2021
Status: active
Page Count: 86
scope:

This standard defines physical layer and data link layer specifications of a new power supply and communication technology over a power line from a dc power source to multiple dc loads with the following conditions:

- Communication speed is 9600 bps or less.

- DC power source is 50 V or less.

- DC load consumes more than 10 W and less than 2 kW.

- The capacity of one power supply is more than 100 W.

- Each receiver has its own physical address (4 b or more).

- Each receiver is connected to the transmitter through a pair of power line wires of 1 km or less.

- Each receiver is connected to the power line in a multi-drop bus or tree topology.

- The transmitter transmits the dc power and the electric signals in the form of electrically changing voltage of the wires through the power line to the receivers and the signals are corresponding to the communication packets that include the control command/data for controlling the dc loads and the target address.

- Each receiver supplies the transmitted and voltage-flattend dc power to the dc loads.

- Each receiver decodes the control command/data and the address from electric signals on the power line and uses them for the connected dc loads if the address matches.

This standard is for dc power line communication technology given the name high power differential signal power line communication (HPDS-PLC).

The relationship between this standard and known electromagnetic compatibility (EMC) regulations is also addressed.

Purpose

The purpose of this standard is to define how to supply power and transmit a control command or data through a power line to the dc loads in an economical and reliable way, such as:

- Light-emitting diode (LED) lighting

- DC motor

- DC actuator

- Battery control device

- DC home electronic appliances from dc power source, such as alternating current (ac) to dc power conversion device

- Battery

- Uninterruptible power supply (UPS)

- Energy storage system (ESS)

- Renewable dc power generation device, such as a solar panel

This standard provides the following advantages:

- It enables high noise margin and signal-to-noise (S/N) ratio as well as common mode noise rejection (to use the line dc voltage totally as signal range).

- Costs of communication solutions may be reduced or eliminated by adopting simple circuits.

- Cost of controlling LED lighting or dc loads may be reduced by eliminating electrolytic capacitors for ac to dc conversion that frequently cause failures and shorten the life span of the loads.

- It makes it possible to avoid efficiency problems due to the double conversions of dc→ac→dc in the power supply process from renewable energy generation.
