Switchsync PWC600 is a point-on-wave controller for high-voltage circuit breakers. Its purpose
is to delay circuit breaker operation commands such that current inception or current
interruption occurs at a phase angle that minimizes stress on the switched load or the circuit
breaker. The PWC600 device (IED, intelligent electronic device) is usually installed in the
control room in the bay control cabinet, where all required signals are present.

For more information on connections, see Section 7.1.
3.3 Functioning principle
The connection of PWC600 in a power system and its high-level functioning principle can be
understood from
optimal controlled switching instants for each phase from a primary reference signal. In most
cases, the reference is taken from a source side voltage transformer (1). The evaluation
considers the design and connection configuration of the load as well as the dielectric and
mechanical characteristics of the circuit breaker. Consequently, it issues a synchronized
opening or closing command to the respective operating coil (2 or 3) of each circuit breaker
pole.
Figure 3. Upon receiving an Open or Close command, PWC600 evaluates the
Figure 3:Overview of PWC600 integration in a power system
PWC600 also monitors the electrical and mechanical health of the circuit breaker as well as the
performance of controlled switching during the previous operation. This information is
obtained by detection the instants of inception or interruption of the primary feedback signal,
which can be load current (4) or load side voltage (5). If no suitable primary feedback signals
are available, monitoring is based on the changeover instants of CB auxiliary contacts 52a/NO
(6) and 52b/NC (7). From the available feedback signals, PWC600 calculates the target error
(difference between expected switching time and actual switching time from last operation)
and applies a timing correction in the next operation. This process is known as “adaptive
correction”.
Refer to
Section 4.4.2 and Section 4.5 for more details on adaptation and monitoring.
PWC600 also has a facility for measuring CB operating times during pre-commissioning
through temporarily connecting to the primary contacts of individual circuit breaker poles.
Figure 4 shows a block diagram of the interfaces to PWC600. The source side voltage, load
side voltage and load current are connected to the Analog input module (or alternatively
received on an IEC 61850-9-2(LE) compliant process bus). Incoming Open or Close commands
and output commands to the circuit breaker coils are connected to the binary input & output
modules. Also, the pole-wise auxiliary contacts and spring charge level (applicable for specific
drive designs) indicators are connected to binary input module. The power supply to the
PWC600 is provided through Power supply module. Alarms related to the health of the circuit
breaker as well as the performance of controlled switching operations can be generated by
relay contacts on the Binary output modules. The PWC600 IED continuously monitors itself
and in event of any internal failure, generates Internal relay failure (IRF) alarm. The user may
interact with PWC600 through the local user interface (LHMI) or through a web interface
(WHMI). Like for all ABB Relion IEDs, settings and configuration of PWC600 are prepared in
PCM600 tool.

3.4 Application overview
Controlled switching, provided by Switchsync PWC600, is used for minimizing harmful
electrical transients upon planned switching of loads such as capacitor banks, shunt reactors,
power transformers, and power cables. The method is also gaining acceptance for reenergizing of EHV transmission lines, and replacing traditional pre-insertion resistors.
3.4.1 Common applications
The most common applications of controlled switching are listed below. Note that PWC600 is
intended only for intentional switching operations, not for protection trips.
Shunt capacitor banks
Basic aim is to control energization to minimize the voltage transients as well as inrush
currents. To improve interrupting performance, controlled opening can also be utilized.
Shunt reactors
Basic aim is to control de-energization to ensure reignition-free current interruption. In
addition, controlled closing also serves as a useful method for minimizing inrush currents.

GUID-AFC0A8F0-28AC-4E13-8513-78FF52B53283 v3

Power transformers
Basic aim is to control energization to minimize inrush currents. This is enabled by controlled
de-energization, to set a repeatable residual flux pattern, which is taken into account for the
subsequent energization.
Unloaded transmission lines and power cables
Basic aim is to control energization to minimize overvoltage transients and to prevent missing
current zeroes on fully compensated cables. To improve interrupting performance, controlled
opening can also be utilized.
In a 1½ circuit breakers arrangement, the middle (tie) breaker is connected to a load on each
end. The same is applicable to every breaker in a ring layout. These two loads may be of the
same type but more often they are different.
The traditional approach to optimize controlled switching of both loads is to install two pointon-wave (POW) controllers for the breaker, together with a hardware logic for transferring
control to the appropriate POW controller. PWC600 1.1 and higher can accommodate these
functionalities in a single device through a feature called Setting Groups, which allows
automatic selection of different parameter sets based on external signals or conditions.
Variable applications, where setting groups are beneficial, include:
•For the tie breaker in 1½-CB or ring arrangements, select the appropriate reference source
and switching strategy depending on the status of adjacent switches and/or voltage
sources.
•In a double-busbar arrangement, select the appropriate busbar VT as reference, without
the need for external circuits for switching the VT signals.
•For power transformers, apply a fallback strategy for closing (assuming zero residual flux)
whenever the CB was opened not by PWC600.
•For loads with variable electrical configuration, e.g. switchable earthing of neutral point,
apply the optimal switching strategy in all cases.
•For any application, bypass the controlled switching functionality whenever an external or
internal binary signal is asserted.
•For FAT or similar situations, where the actual CB is switching low voltage, provide a set of
alternate CB settings (e.g. RDDS) that does not interfere with the original settings to be
applied in the high-voltage grid.

3.6 Communication
The IED supports communication protocols IEC61850-8-1 and HTTPS over Ethernet, and IEC
61850-9-2(LE) over separate Ethernet process bus.
All operational information and controls are available through these protocols. However, some
communication functionality, for example, horizontal communication (GOOSE) between the
IEDs, is only enabled by the IEC 61850-8-1 communication protocol.
Waveform (disturbance) files are accessed using IEC 61850 or the Web interface. Disturbance
files are also available to any Ethernet based application in the standard COMTRADE format.
The IED can send binary signals to other IEDs (so called horizontal communication) using the
IEC 61850-8-1 GOOSE (Generic Object Oriented Substation Event) profile. Binary GOOSE
messaging can, for example, be employed for protection and interlocking-based protection
schemes. The IED meets the GOOSE performance requirements for tripping applications in
distribution substations, as defined by the IEC 61850 standard. Furthermore, the IED supports
Section 31MRK 511 463 A
Switchsync PWC600 overview
the sending and receiving of analog values using GOOSE messaging. Analog GOOSE
messaging enables fast transfer of analog measurement values over the station. The IED
interoperates with other IEC 61850 compliant IEDs, tools and systems and simultaneously
reports events to five different clients on the IEC 61850 station bus. IEC 61850-9-2(LE) is
supported for subscribing to current and voltage signals in digital sampled value format.
All communication connectors, except for the front port connector, are placed on the
integrated communication module. The IED is connected to Ethernet-based communication
systems via the RJ-45 connector (10/100BASE-TX) or the fibre-optic multimode LC connector
(100BASE-FX).
The IED supports the following time synchronization methods with a timestamping resolution
of 1 ms:
Ethernet communication based:
•SNTP (simple network time protocol)
With special time synchronization wiring:
•IRIG-B
•PPS (pulse per second)
PPS signals are used for IEC 61850-9-2(LE) process synchronisation with accuracy of 4 µs.

When using PCM600 for writing to the IED, ensure that the LHMI or WHMI is not
in a menu position where settings can be changed. Only one active writing
transaction, from LHMI, WHMI, or PCM600, is allowed at a time.
With the individual tool components, you can perform different tasks and functions. PCM600
can operate with various topologies, depending on the customer needs.

3.7.1 Connectivity packages
A connectivity package is a software component that consists of executable code and data
which enable system tools to communicate with a specific type of IED. Connectivity packages
are used to create configuration structures in PCM600.
A connectivity package with its associated IED Module(s) includes all of the data which is used
to describe the IED. For example it contains a list of what parameters exist, which data format
is used, the units, the setting range, the access rights and visibility of the parameter. In
addition it contains code which allows software packages in PCM600 to properly
communicate with the IED. It also allows for localization of text even when it is read from the
IED in a standard format such as COMTRADE.
The connectivity package for PWC600 includes a product specific tool, Switchsync Setting
Tool (SST), for entering the required settings for the application. SST comes with a library of
ABB circuit breakers that can be used for controlled switching.
Update Manager is a tool that helps installing the appropriate connectivity package versions
for different system products and tools. Update Manager is included with PCM600.
