Basics - connecting to the power transmission grid 1(3)
The new connection shall be defined taking into
account:
•
Power of required consumption and/or generation, connection
requirements, and location of the connection
•
Impacts on the system security of the grid and on the
environment
•
Disadvantage caused by increasing outages and
disturbances on regional power generation and consumption
•
Technical implementation options and costs
Technical solutions:
•
Voltage level (110, 220,400 kV)
•
Connection to a substation or transmission line
•
Protection and compatibility of electrical equipment
•
Energy measurement interfaces and data communications
The connection must conform to the terms of
connection
• Fingrid Oyj's general terms of connection
• Specifications for the operational performance of power plants

Substation connection
A substation connection is a connection to the Fingrid`s 400 kV, 220 kV or 110 kV substation
The connection shall be agreed in the Connection Agreement containing the fees, rights and
obligations
The customer is responsible for the construction of its own power line connection
Fingrid is responsible for the necessary technical arrangements at its substation or, if necessary,
Fingrid builds a new substation.
Production and/or loads more
than 25 MVA must be
connected to a substation
Petri Parviainen Fingrid, 18.3.2015

110 kV Powerline Connection
A transmission line connection is a branch line or substation
which is connected to a 110 kV transmission line
The connection shall be agreed on Connection Agreement
including the fees, rights and obligations
The maximum allowed unit size of a transformer connected to
a transmission line is 25 MVA
Lots of regulation to take into account ...

Connection of Power Plant
Power plants with a nominal power of more than 0.5 MVA connected to
the Finnish power system must fulfil The Specifications for the
Operational Performance of Power Plants (VJV),
A power plant:
– in excess of 250 MVA is connected to a 400 kV substation
– less than 250 MVA can be connected to a 110 kV substation
– the following can be connected to a 110 kV transmission line
 power plant of less than 5 MVA
 power plant of a maximum of 25 MVA when the short-circuit current fed
by the power plant to the main grid is at the most 1.2 times the rated
current of the power plant
 Customer is responsible for the disconnection relays of its power plant.
These relays must:
– trip the power plant during the high-speed automatic reclosing of the
transmission line ( data communication access will be provided to
the site by Fingrid and it is included in the connection fee)
– contain at least frequency, zero voltage and undervoltage relays
Real-time information required from the customer:
– active power, reactive power and state information of switching
devices
– Update cycle of real-time exchange shall be at least 3 min
– FEN network, protocols: elcom, ICCP, IEC 60870-5-104
