The electrical installations of the future 3 MFM - Multi Functional Modules 4 ABB's experience ABB (www.abb.com) is a leader in power and automation technologies that enable utility and industry customers to improve their performance while lowering environmental impact. The ABB Group of companies operates in around 100 countries and employs about 150,000 people. Multi Functional Modules (MFMs) Utility companies face the challenge of rapidly connecting an ever-increasing number of energy sources to the electrical network, without compromising the overall quality of To meet this need, ABB has...

The electrical installations of the future ABB's response to the new requirements of the high- and medium-voltage electrical distribution market is provided in the form of innovative and compact MFMs (Multi Functional Modules) capable of intelligently combining, in a single product, the functions of a high-voltage module, power transformer, medium-voltage switchgear and control and protection. New challenges for the world of electrical distribution – Continually changing demands – Reduced installation and commissioning times – Increasing reliability requirements Reliability & availability –...

MFM - Multi Functional Module MFMs cover a range of equipment for electrical installations, completely assembled and tested at the factory, easy to transport and install. Combining the modules makes it possible to create any type of mobile or fixed stations. ABB's MFMs are an optimized solution for fixed or temporary nstallations for distribution or generation. The use of MFMs entails significant reductions in installation times and requires minimum civil works. The compact dimensions enable transport with common Version ready for connection to the high-voltage network by means of cables...

The easy loading and unloading from the semitrailer without the use of a crane, facilitates positioning even in narrow areas near to high-voltage lines. MFMs are customizable via software and hardware applications. They can be fitted with accessories such as wheels for road transport, hydraulic lifting and leveling system, remote monitoring and control system, etc. Version ready for connection to the high-voltage network by means of aluminum cords. Available also in a version ready for connection to the high-voltage network by means of cables fitted with couplings. The couplings make it...

MFM - Multi Functional Module Example of 40 MVA 145/170 kV MFM Double Circuit Breaker module Version ready for connection to the high-voltage network by means of cables fitted with couplings. The module is fitted with a double high-voltage circuit breaker and inductive voltage transformers (HV side). Typical single-line diagram Medium-Voltage section High-Voltage section

Application example of MFMs to create an H-configuration station The example shows how it is possible to create an H station using only two MFMs. There are many elements of this solution that differ from a traditional solution: it occupies a very small area, needs less design engineering, requires minimum civil works, offers logistical simplicity owing to its easy transport and installation, meaning less labor and a reduced commitment for assembly and testing on site. Typical single-line diagram High-Voltage section Medium-Voltage section

MFM - Multi Functional Module Transportability MFMs offer excellent transportability. The overall dimensions are such as to allow transport with normal commercial vehicles, and thanks to the availability of a lifting system it is MFM lifted utilizing its own hydraulic jacks. 220 kV MFM on trailer ready for transport. possible to perform the loading and unloading and positioning operations on site without the aid of a crane or lifting equipment. Inserting the trailer ready for transport.

MFM - Multi Functional Module High-voltage section The high-voltage part of the MFM is based on the PASS (Plug and Switch System), a family of hybrid modules. The term "hybrid" indicates the combination of traditional air-insulated switchgear (AIS) and SF6 gas-insulated module (GIS), therefore taking advantage of both of these different This hybrid solution uses already existing and tested, gas- nsulated switching devices, but also utilizes a conventional and very reliable AIS busbar. All functions (with the exception of ring-core current transformers) are integrated into a single SF6...

MFM - Multi Functional Module Components Medium voltage section The MFM unit is complete with a medium-voltage switchgear with relays for protection and control of all elements. The back up batteries and the charging system are also in the MV section. The connection between the transformer and the mediumvoltage switchgear can be made by cable or directly by busbar according to the type of configuration. The protection and control system uses ABB relays of the Relion® family. The protection system makes it possible to monitor the statuses of all the switchgear and controlgear and guarantees...

Power transformer section The MFM unit is fitted with a power transformer which, depending on the configurations, can be the central and supporting structure of the entire module, integrating both the high- and medium-voltage switchgear and controlgear. ABB’s power transformers continuously undergo research, thus making it possible to offer constantly to its customers the highest quality and technological standards. The range The Range of transformers available for the MFM unit have power ratings between 10 and 63 MVA and voltages up to 245 kV, offering ideal solutions for all applications,...

MFM - Multi Functional Module Components MFM control module Control of the MFM module is obtained by the usage of ABB Relion® IEDs, family, collecting all status and interlocking logics from all equipment. The same IED, for the medium voltage section, is simultaneously performing the protection and metering functions. ABB Relion® units are designed in accordance with the international standard IEC61850, which allows easy integration of all control, monitoring, metering and protection functions. The integration between the Relion® units and the COM600 module perfectly meets all...
