Automatic Voltage Regulators (AVRs)

4243 en - 2012.10 / e

LEROY-SOMER

• Power: It varies according to the type of

eld excitation (3 types).

- AREP: The AVR is powered by two auxiliary

windings which are independent of the

voltage sensing circuit.

The rst winding has a voltage in proportion

with that of the alternator and the second

has a voltage in proportion with the stator

current.

- PMG: A permanent magnet generator

(PMG) added to the alternator supplies the

AVR with voltage which is independent of

the main alternator winding.

- SHUNT: The AVR is powered by the main

winding (140 V – 50/60 Hz).

10A fast fuses externally mounted

the D 510C must be used in the three

cases.

• Battery: This is used to supply the AVR

with between 11 V and 30 V. It must always

be present.

The battery supply must be

protected by a 1 A temporised fuse•

• Mains: This input is dedicated to the

measure phase-to-phase mains voltage

which will be taken as the reference when

voltage matching is performed.

• Alternator voltage: This input measures

the alternator output voltage to the AVR in:

- three-phase (U, V, W)

- single-phase (V, W)

• Current transformer(s): This input

measures the current supplied by the

alternator. It must always be present when

the alternator is running in parallel operation

or at PF or KVAR regulation or stator current

limitation.

• The possible congurations are:

- 1 CT on phase U

- 3 CTs on phases U, V and W

• Temperature sensor(s): These are used

to measure the alternator temperature and

alert the user if there is a rise in temperature.

This measurement can be taken either with

1 PTC or 3 PT100s.

• Communication:

- USB port: This is used to connect the AVR

to a computer and creates the link between

the EasyReg software and the D510.

- CAN port: This is used to connect the AVR

to a bus CAN interpreter in order to exchange

parameters with the D510.

The CAN link is only available in the

CAN version identied by the letter C

(eg: D510-C).

• I/O: This part is used to:

- Enter settings

- Send information from the D510

- Receive information from the alternator

• LEDs: These light-emitting diodes inform

the user whether the AVR is working

correctly or not.

1.2 ‑ Characteristics

The different functions of the D510 are:

- Voltage regulation

- Regulation of the power factor (PF)

- Regulation of the reactive power

- Manual regulation (Iexc)

• Voltage regulation: The D510 regulates

the alternator output voltage. Regulation is

applied to the mean value or the true rms

value (TRMS).

• Regulation of the power factor: The

D510 regulates the power factor. This is

the ratio between the active power

(P = √3*U*I*cos φ) and the apparent power

(S = √3*U*I).

- Inductive P.F. [0; π/2] means that the

current is lagging behind the voltage. The

load is inductive (induction motor,

transformer, etc).

- Capacitive P.F. [π/2; π] means that the

current is leading the voltage. The load is

capacitive (uorescent lighting, etc).

• Regulation of the reactive power:

The D510 regulates the reactive power

(Q = √3*U*I*sin φ) at a xed value.

• Manual regulation: The D510 can

regulate the excitation current.

These functions are selected when setting

the AVR parameters.

2 ‑ HUMAN‑MACHINE INTERFACE

The D510 human-machine interface

consists of 3 elements:

- The USB link

- The I/O

- The LEDs

2.1 ‑ Communication

USB link

The EasyReg software and the D510

communicate via a USB cable (Universal

Serial Bus).

2.2 ‑ Analog I/O

This part of the board allows the operator to

use the inputs to make manual settings and

the outputs to check certain data or to

indicate whether certain AVR functions are

working correctly or not. An external voltage

(0 V – 10 V) is present which can be used as

a reference for an electronic device.

The minimum analogic input setting is 0%

and the maximum is 100%.

External by setting is either:

- from an external potentiometer (1k Ω),

- 4 - 20 mA,

- 0 - 10 V,

- ± 10V.

The two analog inputs can also be used to

achieve digital functions + / -.

NB : make sure that the voltage applied on

analogue input does not exceed 10V.

2.3 ‑ Digital I/O
