EEI-EUROTECH
EEI-EUROTECH Energy Division
From 10 years EEI offers innovative solutions also in fields different than its original tradition, such as the production of energy. In all this time EEI accompanied the birth and growth of important initiatives in the field of renewable energy sources, designing and providing static converters for various types of power system.
From this experience, EEI created “EEI Energy Division,” to give energy producers the best performance, the most advanced technical solutions and the best attention to customer needs, which is EEI’s mission
20kW to 50kW Wind Generator Converter
The energy production from wind source is increasing worldwide and, while on one side there is a constant growth of the maximum power that can be generated by a single machine, on the other side there is great interest for machines having small power for operation in parallel to the mains, as well as stand alone.
EEI has designed an equipment for the parallel connection to the mains of a 20 – 50 kW wind turbine with Synchronous Permanent-Magnet generator or Double Fed Induction generator. This solution allows to avoid
the multipliers of rotations, as well as to supply with variable frequency.
| Power from 20 kW to 50 kW | |
| High reliability for heavy conditions | |
| DSP controlled algorithms with advantage of easy grid connection and good electric power output quality | |
| Customer design for specific Direct Drive PM or DFIG Generator | |
| Self protection functions | |
| Air or water cooling | |
600kW to 3MW Wind Generator Converter
The averaged size of the wind generators is growing from 600 – 800 kW of few years ago to 1000 – 1500 kW of these days. EEI, after the successfully development of the converter regarding a 20 kW wind turbine, has designed and manufactured versions until to 1500 kW.
This equipment has been designed to connect to the mains a wind turbine which is equipped with a synchronous permanent.-magnet generator with double winding, without multipliers of rotations. Each of the windings is supplyed by an inverter so that, in case of an inverter failure, the other one is able to make the turbine run up to the half of the rated power.
EEI design and manufactures also equipment for the connection of wind turbines equipped with Double Fed Induction Generator
| Power from 600 kW to 3 MW | |
| High reliability for heavy conditions | |
| DSP controlled algorithms with advantage of easy grid connection and good electric power output quality | |
| Customer design for specific Direct Drive PM or DFIG Generator | |
| Self protection functions | |
| Air or water cooling | |
100kW to 500kW Photovoltaic Converter
From is strong experience in electronic power conversion system, EEI manufactures and installs photovoltaic converters where high reliability and low maintenance levels are mandatory
EEI’s converting systems, is based on the use of a double step converter, equipped with independent boosters and an AFE (Active Front End) converter interfacing to the grid.
● Multiple DC/DC converters: each boosting section is equipped with an independent MPPT, to increase overall efficiency.
● DC bus bar
● Active Front End (AFE) converter interfacing with the power grid and parallel connectable without problems
| Output power from 100 kW to 500 kW | |
| Input Voltage Range 300 V – 850 V | |
| Double step converter with centralized or distributed Booster | |
| Film capacitors inside; no electrolytic ones to improve converter lifetime | |
| High conversion efficiency | |
| Converters directly parallelable | |
| 5 years warranty | |
Hydropower – CHP – Fuel Cells
The systems for distributed production of energy are generating a growing interest among industry.
EEI is able to offer its solutions for a wide range of hydropower applications, from mini-hydro turbines to larger installations, with the power of several MW.
EEI also manufactures systems for CHP (simultaneous production of electricity and heat) and for Fuel Cells grid connections.
All those technology are playing a key role in improving the efficiency of our energy production system.
| Micro-turbines and Turbogas | |
| OCR Turbines (Biomass) | |
| Fuel cells | |
| Hydropower application | |
| Customer Tailored Applications |
For the North American market EEI is working in partnership with EUROTECH, witch has been a subsidy of EEI since 1998. EUROTECH with it’s staff of sales and service personnel is available for the North American customers to answer to all the challenges that this particular market branch have. From the smallest applications of 5KW to bigger applications of 3MW, EEI and EUROTECH are the right answer for the market.
