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

REG 316*4’s library of protection functions includes the follow-

ing:

·generator differential (Diff-Gen)

·transformer differential (Diff-Transf )

·definite time over and undercurrent (Current-DT)

·provision for inrush blocking

·peak value overcurrent (Current-Inst)

·voltage-controlled overcurrent (Imax-Umin)

·inverse time overcurrent (Current-Inv)

·directional definite time overcurrent (DirCurrentDT)

protection

·directional inverse time overcurrent (DirCurrentInv)

protection

·definite time NPS (NPS-DT)

·inverse time NPS (NPS-Inv)

·definite time over and undervoltage (Voltage-DT)

·peak value overvoltage (Voltage-Inst)

·underimpedance (Underimped)

·underreactance (MinReactance)

·power protection (Power)

·stator overload (OLoad-Stator)

·rotor overload (OLoad-Rotor)

·frequency (Frequency)

·rate-of-change frequency protection (df/dt)

·overexcitation (Overexcitat)

·inverse time overexcitation (U/f-Inv)

·voltage comparison (Voltage-Bal)

·overtemperature (Overtemp)

·100 % stator ground fault (Stator-EFP)

·100 % rotor ground fault (Rotor-EFP)

·pole slipping (Pole-Slip)

·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.
