IEC 61850-7-410 Extended Models for Conventional Power Plants

IEC TC 57 just published a FDIS defining extensions for conventional power plants and steam turbines:

IEC 61850-7-410 A1 (57/1607/FDIS): Amendment 1 to IEC 61850-7-410 Ed.2:
Communication networks and systems for power utility automation –
Part 7-410: Basic communication structure – Hydro-electric power plants – Communication for monitoring and control

Voting closes 2015-10-09.

The following new Logical Node classes are added to the Hydro Power model standard IEC 61850-7-410 Ed2:

LN	Description
ASEQ	Generic control action sequencer
EBCF	Block control function. This LN will represent one physical device that coordinates the control of the thermal pressure of the steam generator and the electrical power regulation of turbine / generator system.
EFCV	Fuel control valve. This LN will represent the physical device of fuel control valve related to the gas turbine in a thermal power plant.
EGTU	Gas turbine production unit. This LN represents the physical device of the GT and the generator combination in a thermal power plant. It is intended as an extended rating plate that allows settings of data. It also acts as a placeholder for the current operating conditions of the unit.
ESCV	Steam control valve. This LN will represent the physical device of inlet control valve of the steam turbine in a thermal power plant.
ESPD	Speed monitoring. This LN is derived from HSPD.
ESTU	Steam turbine production unit. This LN represents the physical device of the ST and the generator combination in a thermal power plant. It is intended as an extended rating plate that allows settings of data. It also acts as a placeholder for the current operating conditions of the unit.
EUNT	Thermal unit operating mode. The present status of the production unit.
FDBF	Dead-band filter. This LN represents a settable filter for dead-band.
FMTX	Trip matrix. This LN represents a matrix for linking various trip functions to equipment that shall be tripped or controlled during a fault.
GUNT	Production unit operating mode. The present status of the production unit.
PTUR	Used for detection of under resistance, e.g. due to stator or rotor earth-faults.
SECW	Supervision of electrical conductivity in water. This logical node represents a system for monitoring of electrical conductivity in water.
TECW	Measurement of electrical conductivity in water. This logical node represents a generic device for measuring the conductivity in water.
