Section 3 Switchsync PWC600 overview

3.1Introduction

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.

3.3Functioning principle

The connection of PWC600 in a power system and its high-level functioning principle can be understood from Figure 3. Upon receiving an Open or Close command, PWC600 evaluates the 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: 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.

3.4Application 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.

3.4.1Common 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.

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.

3.4.2Variable applications

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 point- on-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.

3.5User interfaces

The user can interact with Switchsync PWC600 in several ways.

•Local Human-Machine Interface (LHMI) on the front panel of the IED, featuring LCD screen, pushbuttons and status LEDs

•Web interface via web browser

•Various tools in Protection and Control Manager PCM600, installed on a PC

3.6Communication

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

21

User manual

Section 3	1MRK 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.

3.7PCM600 tool

Protection and Control IED Manager PCM600 offers all the necessary functionality to work throughout all stages of the IED life cycle.

•Planning

•Engineering

•Commissioning

•Operation and disturbance handling

•Functional analysis

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.

For more information, see PCM600 documentation.

3.7.1Connectivity 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.

3.8Environmental aspects

3.8.1Sustainable development

Sustainability has been taken into account from the beginning of the product design including the pro-environmental manufacturing process, long life time, operation reliability and disposing of the IED.

The choice of materials and the suppliers have been made according to the EU RoHS directive (2002/95/EC). This directive limits the use of hazardous substances which are the following:

Table 1: Maximum concentration values by weight per homogeneous material

Substance	Permitted maximum concentration
Lead - Pb	0.1%
Mercury - Hg	0.1%
Cadmium - Cd	0.01%
Hexavalent Chromium Cr (VI)	0.1%
Polybrominated biphenyls - PBB	0.1%
Polybrominated diphenyl ethers - PBDE	0.1%

Operational reliability and long life time have been assured with extensive testing during the design and manufacturing processes. Moreover, long life time is supported by maintenance and repair services as well as by the availability of spare parts.

Design and manufacturing have been done under a certified environmental system. The effectiveness of the environmental system is constantly evaluated by an external auditing body. We follow environmental rules and regulations systematically to evaluate their effect on our products and processes.

3.8.2Disposing of the IED
