1.1 Application
The PCS-9611 relay is a protection, control and monitoring unit for various primary equipments
(such as overhead line, underground cable and transformer etc.) on solidly grounded, impedance
grounded, Peterson coil grounded and ungrounded system. This relay is suitable for wall surface
mounted indoors or outdoors or flush mounted into a control panel.
This relay can sample the analog values from the traditional instrument transformers, or receive
the sampled values from the electronic current and voltage transformers (via a merging unit). The
binary inputs and outputs of this relay can be configured according to the demands of a practical
engineering through the PCS-PC configuration tool auxiliary software, which can meet some
special requirements of protection and control functions.
This relay can fully support the IEC61850 communication protocol and GOOSE function, and can
completely meet the demands of a modern digitalized substation.

bus and intelligent I/O ports, and the hardware is in module design and can be configured
flexibly, featuring interchangeability and easy extension and maintenance.
zModularized hardware design makes this relay be easily upgraded or repaired by a qualified
service person. Various function optional modules can satisfy various situations according to
the different requirements of the users.
zThe adoption of 16-bit A/D converter and the dual-channel sampling technology can ensure
the accuracy and reliability of protection sampling and the correctness of protection operation.
It is also provides dedicated current transformers for metering, and ensures the high accuracy
of telemetering with 48-point high speed sampling rate per cycle.
zThis device can sample the analog values from the traditional instrument transformers, or
receive the sampled values from the electronic transformers. It can support the protocol
IEC60044-8, IEC61850-9-2 and GOOSE.
zVarious algorithms for protection and measurement have been completed in this device for
the feature of electronic transformer sampling, such as the error prevention method of
multi-algorithms data anomaly for the digital channels, to realize high accuracy and reliability
under various conditions of network faults or communication interruption.
zThis device has powerful GOOSE functions, and the connection and cooperation between
some devices can be realized without using electrical cables, to facilitate the realization of
such functions as simple bus differential protection, overload interlock shedding function and
backup automatic transfer function etc.
zThis device has fully realized the technology to integrate six functions into one device:
protection, measurement, control, remote signaling, merging unit function and remote module

functions, to improve the reliability.
zVarious methods of GPS time synchronization are supported in this relay, including SNTP,
IEEE1588 (V2), pulse per second (PPS) and IRIG-B synchronization.
zThe protection modules are completely separated from other modules, and are independent
in both hardware and software. The protection functions do not depend on the communication
network, so the failure of communication network will not affect the normal operation of the
protection functions.
zMature protection configuration, fast speed and high security performance can meet the
practical requirements. Each protective element is independent, so it is very convenient for
whether adopting the selected protective element.
zThis device constantly measures and calculates a large amount of analog quantities, such as
phase voltage, phase-to-phase voltage, neutral voltage, phase current, neutral current, active
power, reactive power, power factor and frequency etc.
