ABB IEC61850 and Ethernet Redundancy Introduction and Applications

IEC 61850 and Ethernet redundancy

Communication services in the substation

– IEC 61850-8-1 part allows the elimination of copper wires between relays on a horizontal level, i.e. relay-to-relay communication – substation bus;

IEC 61850-9-2LE allows the sharing of digitised information from transformers or sensors with other relays in a standardised way – process bus.

These services are categorised as client-server services:

– The MMS traffic, defined in IEC 61850-8-1. allows MMS clients such as SCADA, OPC servers or gateways to access all IED objects “vertically”.

This traffic flows on the station bus and the process bus.

Real-time services:

– The GOOSE flow, as defined in IEC 61850-8-1. which allows the IED to exchange data “horizontally” between machine rooms, or “vertically” between the process level and the machine room level.

In particular, status signals and trip signals are usually also used for interlocking. These information flows are usually transmitted via the station bus and/or the process bus.

– The SV (Sampled Value) flow is defined in IEC 61850-9-2 and is used to transmit voltage and current samples.

This flow is usually on the process bus, dcs-sis.com but can also flow via the station bus, e.g. for busbar protection, centralised protection and control, and phase measurement.

Generic Object-Oriented System Events (GOOSE)

– Standardised horizontal communication

– Replaces hard wiring between relays and controllers

– GOOSE is used to broadcast events between relays in a substation.

– The GOOSE communication link between relays is monitored and controlled by cyclically sending data.

– Ethernet technology provides a fast and reliable station bus for data transfer.

Hitachi Energy 560NMD01 Managed Layer 2 Switch

Applications

The 560NMD01 Top Hat DIN-Rail Appliance is a managed Layer 2 switch.

It provides four Fast Ethernet RJ45 ports with automatic MDI/X (Automatic Cross Detection and Correction) and a 2-wire SDSL interface.

The SDSL interface can be used to connect sites with distances of up to 20 km (copper cable, 0.8 mm diameter).

Thanks to the (fast) Spanning Tree Protocol, the switch enables a redundant topology.

For documentation purposes, Ethernet ports are labelled with numbers 1-4. There are no special uplink ports. All ports are functionally identical.

The SDSL ports are externally connected via backplane or expansion connectors. The connection (link) and speed status of all Ethernet and SDSL ports is indicated by LEDs on the front panel.

The switch “learns” Ethernet addresses by analysing received frames.

The addresses learned in this way are stored dcs-sis.com in the address table (up to 2048 entries) and are used to forward the frames to the correct interface.

Frames are forwarded to all interfaces only if they are received with a wide or multicast address, or if the destination address is not found in the address table.

If an entry in the address table is not acknowledged by the corresponding received frame, it is deleted after a maximum of 304 seconds (default).

IEEE 802.1Q-compliant VLAN configuration is supported. Frames can be transparently forwarded or assigned to (access or trunk) VLANs.

The switch can support quality of service if IEEE 802.1p-compliant frame formats are used. The switch can divide outbound frames into up to four priority-controlled queues.

The device has a wide-range power supply, requiring a voltage between 24 and 60 V. The switch can be used with a wide range of power supplies.

The Ethernet interface, SDSL, RS232 (Con 0) and the expansion bus interface (Ext) can be plugged in during operation (hot-swap).

Connectors and indicators

The 560NMD01 device provides four equivalent Ethernet interfaces with RJ-45 connectors, an SDSL interface and an RS232 interface that are

for configuration and transfer of serial data. Each RJ-45 port can be connected via Cat.3 (10Mbps) or Cat.5 (100Mbps) network cable.

for internal communications up to 100 metres. Support for MDI/X means that crossover Ethernet cables are not required.

MOOG Dual PWM Amplifier G123-814

Application Notes

Scope

These application notes are a guide to applying the G123-814 Dual PWM Amplifier. They show you how to install, connect and adjust the PWM amplifier.

They do not cover how to select a proportional valve or how to design a closed-loop system.

Instructions

The G123-814 Dual PWM Amplifier is used to drive two coils of a three position 24V solenoid proportional valve.

It is designed for low-end closed-loop applications. It allows the use of very low cost proportional valves where much more expensive servo valves would normally be required.

Using it with the companion servo amplifier G122-824 and a proportional valve produces an economical closed loop solution.

Applicability

The G123-814-001 has a closed dcs-sis.com loop configuration and is used with Hydrolux WP series proportional valves.

Important specifications considered include 24V @ 800mA coil and 12% spool overlap.

Output current is 25% higher than rated to ensure that maximum flow is not unduly affected by valve production tolerances and spool Bernoulli forces.

Deadband compensation circuitry to eliminate spool overlap has been optimised for flow bench and field applications. Deadband compensation is not user adjustable. Applying this amplifier

Apply this amplifier to other valves with the same specifications to obtain the same performance as Hydrolux valves.

The G12-814 is not suitable for conventional open-loop proportional valve applications. A zero flow condition is highly unlikely as the deadband compensation circuit cancels out spool overlap.

Zero flow conditions are unlikely with zero coil current as the deadband compensation circuit cancels out spool overlap.

Mounting

Installation consists of mounting a horizontal DIN rail to the vertical rear surface of an industrial steel enclosure.

The rail release clips on the G123-814 should face downward to allow front panel and terminal markings to be clearly readable and to allow cooling airflow to the internal electronics.

An important consideration for module placement is electromagnetic interference (EMI) from other equipment in the enclosure.

For example, VFs and AC servo drives generate high levels of EMI. be sure to check other equipment for EMC compliance before placing it near the G123-814.

Cooling

Vents at the top and bottom of the G123-814 chassis provide cooling for internal electronic equipment. These vents should be kept clear.

It is important to ensure that the equipment below does not generate hot exhaust gases that could heat the G123-814.

Emerson A6410 Dual Channel Valve and Enclosure Expansion Monitor

The Valve and Shell Expansion Monitor is designed to provide high reliability for the plant’s most critical rotating machinery.

This 1-slot monitor is used with other AMS 6500 monitors to form a complete API 670 machinery protection monitor.

Applications include steam, gas, compressors and water turbines.

The primary function of the Valve and Case Expansion Monitor is to accurately monitor valve position and case expansion.

The main function of the valve and case expansion monitor is to accurately monitor valve position and case expansion and to reliably protect the machinery by comparing parameters with alarm set points, actuated alarms and relays.

Valve position is a measurement of the position of the main steam inlet valve stem, usually displayed as a percentage of opening.

The valve position measurement provides the operator with an indication of the current load on the turbine.

Casing expansion monitoring typically consists of two inductive displacement transducers (or LVDTs) mounted axially, parallel to the shaft, on either side of the turbine casing.

Unlike non-contact eddy current sensors, inductive sensors are contact sensors.

Casing expansion monitoring is important during startup so that the proper expansion rate can be monitored on both sides of the turbine casing.

Because the turbine can slide on the guide rails as it expands, if neither side is free to expand, the turbine will “bend” (housing flex), causing the rotor to collide with the housing.

Channel 1 can be used to measure static values, such as case expansion, as well as dynamic quantities

such as displacement, angle, force, torsion or other physical quantities measured by inductive sensors.

Physical quantities measured by inductive sensors. Channel 2 is used for static measurements and relative displacements (relative to channel 1).

The AMS 6500 Machinery Health Monitor dcs-sis.com is an integral part of PlantWeb® and AMS software.

PlantWeb provides integrated machine health operation in conjunction with the Ovation® and DeltaV™ process control systems.

AMS software provides maintenance personnel with advanced predictive and performance diagnostic tools to accurately determine machine failures at an early stage.
