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-Explorer 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.
The function diagram of this relay is shown in Figure 1.1-1.

This 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.
Various methods of GPS time synchronization are supported in this relay, including SNTP,
pulse per second (PPS) and IRIG-B synchronization.
The 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.
Mature 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.
This 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.
The human machine interface (HMI) with a small control module (a 240×128-dot LCD, a 9-key
keypad and 20 LED indicators) on the front panel is very friendly and convenient to the user.
This device can communicate with a SAS or RTU via different communication intermediates:
Ethernet network, RS-485 serial ports. The communication protocol of this device is optional:
IEC61850, IEC60870-5-103 or DNP3.0.
This device can detect the tripping circuit of the circuit breaker and monitor the operation
(close or trip) time of a circuit breaker by checking the auxiliary contacts of the circuit breaker.
Complete event recording function is provided: 64 latest protection operation reports, 1024
latest supervision records, 1024 latest control operation records, 1024 latest user operation
