SIPLINK can connect two or more separate medium voltage AC grids with different voltages, frequencies or phase angels


SIPLINK in Overview

SIPLINK is capable of connecting two or more MV AC nets with different voltages, frequencies, phase angles or neutral point connection.

SIPLINK controls the load flow between connected networks and the reactive power in all connected networks.

This allows the following applications:

  • Connection of MV networks (MVDC Back to Back)

  • Ship to Shore connections

  • High availability for industry grids

Industrial networks

High availability for industry grids

SIPLINK Y-circuit

  • Secure busbar is simultaneously connected with 2 networks

  • Secure busbar is an “oscillating” load. Power is obtained to a greater extent from the network which has more reserves

  • Controlled exchange of energy between the two feeding networks

  • No increase in short-circuit power

SIPLINK Multi Feed

  • Voltage dips now subject only to the opening of the infeed switch

  • Every secure busbar is simultaneously connected to all other busbars

  • SIPLINK allows the load to be transferred immediately if a fault occurs in any incoming supply

Shore-to-ship connection

SIPLINK - shore-to-ship connectionSIPLINK – the intelligent link from Siemens – offers different combinations of frequencies and voltages for the shore-to-ship connection, primarily of course the future standard-compliant values 6.6 and 11 kV, 50 and 60 Hz.

SIPLINK helps save costs and reduce emissions of CO2, SOx, NOx, fine dust and noise in the harbor.

Network Coupling

Connection of MV networks

SIPLINK offers the following advantages:

  • A controlled exchange of power between two MV networks, for example for balancing peak loads

  • Reducing the cost of expensive balancing power

  • Reactive power compensation for both networks

  • No increase in short-circuit power
