DEIF Hybrid microgrid controllers

Hybrid microgrid controllers

Our complete range of hybrid microgrid controllers helps you enjoy the benefits of hybrid power generation in a wide range of applications. You can design, run, and supervise greenfield hybrid power plants, or add hybrid capabilities to existing power plants using our controllers for brownfield applications including power rental.

Greenfield or brownfield?

In greenfield applications, you design a hybrid power plant with DEIF power/energy management systems (PMS/EMS) from the ground up. DEIF controllers allow you to design for a wide range of solutions with built-in features that ensure flexibility, scalability, reliability, and redundancy.

In brownfield applications, you integrate single DEIF hybrid microgrid controllers in existing power plants with 3rd party controllers or a pre-existing EMS/PMS, expanding the solution with a wide range of control options. You can also deploy them in standalone off-grid or mains parallel applications.

Hybrid capabilities in a wide range of applications

DEIF hybrid microgrid controllers handle all renewable power sources, from PV panels to wind turbines, as well as battery energy storage solutions (ESS). In addition, they can interface with mains and genset controllers, enabling you to combine a wide range of power sources in your hybrid power plant.

Compatible with all SCADA systems and a wide range of PV and ESS inverters and battery management systems, our controllers are suitable for smart energy control in many different off-grid or mains parallel applications such as micro grids and nano grids; commercial and industrial sites; and events such as concerts, festivals, or camps.

DEIF’s Digital Automatic Voltage Regulators (AVR)

DEIF’s Digital voltage controllers (Digital Automatic Voltage Regulators (AVR))

DVC-550 Features: The DVC-550 Digital Voltage Controller by DEIF is designed to provide precise automatic voltage control for alternators with SHUNT, AREP, or PMG excitation. It monitors and regulates the alternator output, ensuring stable and reliable performance. The DVC-550 includes several protections and functions to keep the alternator running in full safe operation. It can improve genset performance, delivering up to a 10% increase in normal load impact capability.

DVC-350 Features: The DVC-350 Digital Automatic Voltage Regulator by DEIF is a cost-effective solution for maintaining efficient and safe power systems. It offers a wide range of alternator protections and functions, including reactive and line droop compensation, a soft start function, voltage soft recovery, and a load acceptance module (LAM) function. The DVC-350 is ideal for volume production and can be regulated using a built-in analogue potentiometer if needed

In summary, a Digital AVR designed for alternators with SHUNT, AREP, or PMG excitation is a vital component for ensuring stable and reliable voltage regulation. DEIF’s DVC-550 and DVC-350 offer advanced features and benefits that enhance the performance and reliability of power systems.

DEIF’s Digital voltage controllers

DEIF’s Digital voltage controllers are Digital Automatic Voltage Regulators (AVR) that are essential components designed for alternators with SHUNT, AREP, or PMG excitation. This device plays a crucial role in monitoring and regulating the alternator’s output voltage to ensure stable and reliable performance.

Excitation Methods:

SHUNT Excitation: SHUNT excitation involves using the alternator’s output to power the AVR. This method is commonly used in smaller alternators and provides a simple and cost-effective solution for voltage regulation.

AREP Excitation: AREP (Auxiliary Winding Regulation Excitation Principle) utilizes auxiliary windings in the alternator to supply power to the AVR. This method enhances the alternator’s ability to handle transient loads and provides better voltage stability.

PMG Excitation: PMG (Permanent Magnet Generator) excitation uses a separate permanent magnet generator to supply power to the AVR. This method offers superior voltage regulation and is ideal for applications requiring high reliability and performance.

Eaton MTL831B IS Mounting on T-section DIN-rail

Mounting on T-section DIN-rail (Figure 1)

Hook the side opposite the central mounting clip onto standard 35mm

DIN46277 T-section rail and push downwards until the unit clicks into

place.

To remove, ease the central clip below the base of the unit outwards

(with a screwdriver) and unhook the clips on the other side.

Mounting on a flat surface (figures 2 and 3)

Turn the unit upside down.

With a screwdriver, apply an anti-clockwise force against the

retaining arm of one of the base clips to release it from its recess.

Hold the arm in this position and slide the clip outwards.

Release the retaining arm to engage the tooth in the base moulding.

Adjust the position of the other two clips with a similar procedure.

Mount on any flat surface using three M4 bolts or screws (or other

suitable fasteners with a shank diameter of 4mm or less) through the

three clips according to the mounting centres shown in figure 3.

Mounting in an ENC8. ENC8-SS, ENC83 or

ENC83-SS enclosure (figure 4)

Remove the upper and/or lower undrilled gland plates and drill

suitable holes for the entry glands required. Possible hole

configurations are listed in the table.

Mount the unit on the internal T-section rail of the enclosure as

described in (1).

Mount the enclosure on any flat surface using four M8 bolts (or other

suitable fasteners with a shank diameter of 8mm or less) through the

four fixed lugs according to the mounting centres shown in figure 4.

Eaton MTL831B IS MECHANICAL INSTALLATION

GETTING STARTED

Installation of the MTL831B multiplexer transmitter is divided into

three main topics.

♦ Mechanical Installation – how to mount the MTL831B and

how it may be fitted into our enclosure.

♦ Electrical Connections – the sensor and highway

connections. If units are installed in our enclosures, it details any

special wiring arrangements.

♦ Configuration-  the address and input mode selection by the

setting of internal switches.

Note:  A new user might find it helpful to set up the system, or a

simple version of it, in an indoor test area to gain familiarisation

before undertaking installation on site.

MECHANICAL INSTALLATION

Location

The MTL831B can be installed in either safe or hazardous areas

(including Zone 0 or Division 1) depending upon the requirements of

the application.

Mounting options

The unit can be mounted on T-section DIN-rail or onto a flat surface.

Eaton has a range of enclosures – ENC8. ENC8-SS, ENC83 or

ENC83-SS – to provide suitable IP67 protection if the transmitter is

located in an exposed area.

Eaton MTL831B IS analogue multiplexer transmitter

Product description

The MTL831B analogue transmitter can transfer a number of

hazardous area input signals to the safe area down a data highway

consisting of a single twisted pair cable. It is intrinsically safe and can

therefore be mounted in Zone 0 hazardous areas or Class I, Division

1 hazardous locations.

The MTL831B can monitor up to 16 inputs from THC or millivolt

sources or up to 15 inputs from 2. 3 or 4-wire RTDs.

Two (i.e. dual redundant) data highway outputs are provided that can

carry both signal and power over distances up to 3km, depending on

the application, the cable and the (noise) environment – see Section

4.4. The highway cables can be simple twisted-wire pairs or pairs of

wire within an IS multi-core cable.

At the other end of the data highway, MTL838B-MBF receivers are

used to translate the information transmitted from the MTL831B. The

MTL838B-MBF provides a Modbus®serial data output representation

of the inputs together with status information.

When the MTL831B transmitter is mounted in the hazardous area,

each data highway mustbe protected by an MTL3052 digital isolator

mounted in the safe area.
