6-in-1 solution: Revenue Metering Power Quality Distributed Fault Recorder Sequence of Events (SoE) Backup Protection Equipment Devices Control
Substation Automation Relay Target Information
– Get all of the information available from a digital relay without replacing the electromechanical one
Add-On Protective Relaying Backup– Under / over frequency relay– Automatic load shed & restore (0.01 Hz with adjustable time delay)– Reclosing relay– Multi-shot automatic reclosing– Synchro-check and LLDB/LBDL supervision– Permit / block reclose– Phase angle, slip frequency, LLDB/LBDL control– Time over-current relay backup– Back up prime TOC relay curve with up to 32 current magnitude and
duration set-points Various Communication protocols
– Modbus– DNP3.0– IEC 61850
Sequence of Events (SoE)
Four types of events:– digital input– relay output– Fault– Set-point
Each input point is programmableto be NO or NC
Programmable status words Programmable De-bounce times 1-256 msec Up to 160 discrete inputs – wet or dry contacts
Fault Recorder 4 measured currents IRIG-B time synchronization Up to 20 minutes of continuous recording
with 256 MB memory Programmable fault thresholds and hysteresis Up to 150 amps fault currents (30 x In) Zero-sequence currents and voltages Current and voltage unbalance Under-voltage, neutral current Ready-to-use fault reports—fault currents magnitude and
duration, coincident volts magnitude, fault waveforms and RMS Distance to fault calculation Multi-feeder (up to 3) fault recorder Waveforms from 2 separate locations (via PAS)
Power Quality Recorder Class A IEC 61000-4-30 Power Quality analysis:
– Sags/swells (dips/over-voltages), interruptions, frequency variations, Flicker, voltage unbalance, harmonic and inter-harmonic voltages
Programmable thresholds and hysteresis Built-in EN50160 statistics & reports Redundant auxiliary power supply for recording major dips & interruptions Harmonics & inter-harmonics according to IEC 61000-4-7 Directional power harmonics and power factor phasors THD, TDD and K-Factors Symmetrical components Flicker measurement according to IEC 61000-4-15 Selectable sampling rate up to 256 samples/cycle Event recorder for logging internal diagnostic events, control events and
I/O operations Waveform & data recorder
Transient Recorder Transient pulses as short as 20μs at 50 Hz (17μs at 60 Hz) Up to 1024 samples per cycle Amplitude relative to ground as per EN 50160 (4 channels) Up to 2kV measurement, 6kV withstand
Case StudySubstation Automation System (SAS) SATEC products (ezPAC, PM175 and PM130) are
the heart of the substation automation system (SAS) solution provided by NPT throughout the entire Russian Federation
Two configurations:– Comprehensive for
220 and 750kV– Standard for 6, 10,
35 and 110 kV
Key Design Concepts
SATEC IEDs provide protection, automation, measurement and control functions
SCADA-system for operational control Open system concept reduces dependency on
vendors Standard protocols for IED and HMI
communication Wide use of Factory Acceptance Testing (FAT) Integration of substation protection and
automatics into control software
SATEC ezPAC SA330 bay controllers are used on lower level to collect digital, analogue information as well as to control switchgear.
Bay controllers RTU SA300-330
PM175
Power Quality Analysis (EN50160, IEEE 1159 and GOST 13109-97)
Time Of Use (TOU) Accuracy Class 0.2S RTC and 10-year calendar Full galvanic isolation Non-volatile memory Registration of parameters on
set-point or time
ezPAC IEC 61850 Protocols
IEC 61850-7-2,3,4– Basic communication structure for substation and
feeder equipment – Abstract communication service interface (ACSI), Common Data classes, Compatible logical node classes and data classes
IEC 61850-8-1– Specific Communication Service Mapping (SCSM) –
Mappings to MMS (ISO 9506-1 and ISO 9506-2) and to ISO/IEC 8802-3
IEC 61850-10– Conformance testing
Implementation in NPT Expert SAS
