1. INTRODUCTION
1.1. General
The numerical generator protection scheme REG 316*4 is one of
the new generation of fully digital protection systems, i.e. the
analogue-to-digital conversion of the measured input variables
takes place immediately after the input transformers and the re-
sulting digital signals are processed exclusively by programmed
micro-processors.
Within the PYRAMID®system for integrated control and protec-
tion, REG 316*4 represents one of the compact generator
protection units.
Because of its compact design, the use of only a few different
hardware units, modular software and continuous self-monitoring
and diagnostic functions, the REG 316*4 scheme optimally fulfils
all the demands and expectations of a modern protection
scheme with respect to efficient economic plant management
and technical performance.
The AVAILABILITY — the ratio between fault-free operating time
and total operational life — is certainly the most important re-
quirement a protection device has to fulfil. As a result of con-
tinuous monitoring, this ratio in the case of REG 316*4 is almost
unity.
Operation, wiring and compactness of the protection are the es-
sence of SIMPLICITY thanks to the interactive, menu-controlled
man/machine communication (HMC) program. Absolute FLEXI-
BILITY of the REG 316*4 scheme, i.e. adaptability to a specific
primary system or existing protection (retrofitting), is assured by
the supplementary functions incorporated in the software and by
the ability to freely assign inputs and outputs via the HMC.
Decades of experience in the protection of generators have gone
into the development of the REG 316*4 to give it the highest
possible degree of RELIABILITY, DISCRIMINATION and STA-
BILITY. Digital processing of all the signals endows the scheme
with ACCURACY and constant SENSITIVITY throughout its
useful life.
The designation “RE. 316*4” is used in the following
sections of these instructions whenever the information
applies to the entire series of devices.

1.2. Application
The REG 316*4 numerical generator protection has been
designed for the high-speed discriminative protection of small
and medium size generators. It can be applied to units with or
without step-up transformer in power utility or industrial power
plants.
REG 316*4 places relatively low requirements on the perform-
ance of c.t’s and v.t’s and is independent of their characteristics.
1.3. Main features

ing:
·generator differential (Diff-Gen)
·transformer differential (Diff-Transf )
·definite time over and undercurrent (Current-DT)

·invers time ground fault overcurrent (I0-Invers)
·breaker failure protection (BreakerFailure)
·supplementary logic functions such as
·supplementary user logic programmed using CAP316
(function plan programming language FUPLA). This
requires systems engineering.
·logic
·timers
·metering
·debounce.
The following measuring and monitoring functions are also avail-
able:
·single-phase measuring function UIfPQ
·three-phase measurement module
·three-phase current plausibility
·three-phase voltage plausibility
·disturbance recorder.
The scheme includes an event memory.
The allocation of the opto-coupler inputs, the LED signals and
the auxiliary relay signal outputs, the setting of the various pa-
rameters, the configuration of the scheme and the display of the
events and system variables are all performed interactively using
the menu-driven HMC (man/machine communication).
REG 316*4 is equipped with serial interfaces for the connection
of a local control PC and for remote communication with the
station control system.
REG 316*4 is also equipped with continuous self-monitoring and
self-diagnostic functions. Suitable testing devices (e.g. test set
XS92b) are available for quantitative testing.
REG 316*4 can be semi-flush or surface mounted or can be in-
stalled in an equipment rack.
