The tag power=converter is used to map a converter: a device allowing power transmission between alternating and direct current (HVDC) electrical power networks. They are often located in a converter substation (605-01-07) comprises an HVDC converter device operating at high voltage.

How to map

Add a node node or area area at the location of the converter and tag it with power=converter and, if known, with the additional keys detailed below. Typically, a converter is placed in a dedicated building called valve hall. In this case add all tags to the building.


Key Value Comment Recommendation
power converter Defines this node node or area area as an HVDC converter. Typically the converter building (valve hall) should get this tag. Mandatory
converter <type of converter> Type of converter. Recommended
voltage <operating voltage> Voltage at which the converter is operated. Recommended
location <location> Physical location of the converter. The default value is indoor. Recommended
operator <cable operator> Name of the company which operates this power converter. Recommended
phases <number of phases> Number of different phase on the alternative side of the converter. Recommended
poles <number of poles> Number of poles on the direct side of the converter. Recommended
frequency <operating frequency> Given frequency in hertz at which the power converter is operating on its alternative side. Optional
rating <rating> Rating in MVA at which the converter is transmuting power. Optional
name <name> Name of this power converter. Optional
ref <reference> Reference of this power converter. Optional

Converter types

Key Value Comment
converter lcc A line-commutated converter (LCC) uses thyristor based valves and is the most common type. This is the default value.
vsc A newer type is the transistor-based voltage source converter (VSC).
back-to-back A back-to-back converter couples two AC networks that are not synchronous or operate at different frequencies. There is no external DC power transmission link
motor_generator Motor generator converters refers to an electromechanical system with rotating electrical machines for converting electrical energy from the public power grid in traction current for the electrical supply of rail vehicles.
