6 PROFILE Electro-technical buildings & stations We construct certified for solar, wind & biogas power: Substations up to 400 kv Transformer stations Solar inverter substations Enterable & compact variants Made of concrete or aluminum Electrical components from renowned manufacturers

7 PROFILE Plant construction Turnkey PV & wind systems with optimized properties We provide adjusted and appropriate solutions and individuell design during the planning, construction and operation of complex, large scale projects but also decentralised energy stations directly at site Project implementation: know-how from one source We guarantee quality and effectivness, inexpensive investment for a longtherm durability of our products We provide experience, expertise and contacts

8 PROFILE Modules and systems Control engineering, modeling of control structures for grid computing, monitoring-, protection- & measuring systems By constructing more than 1,000 installations of all sizes around the world, we have gained practical experience and constantly expand our skills. We exclusively offer specific, detailed and meaningful offers or contracts to our clients. We offer long-term investment security with high quality modules and components of the leading manufacturers.

9 PROFILE Engineering Services We offer expertise and advice for the planning, development and the usage of substations, PV & wind power plants and other applications We support complex construction projects through all trades and stages In cooperation with our partners, we offer calculations with mathematical methods and models for performance calculation and interpretation of the energy grid.

10 PROFILE Planning & Consulting I Cableruns location including the documentation Calculations of short-circuits for DC and AC equipment Calculations of electricity-carrying capacity Cable sizing for DC and AC equipment Working out of drafts for main supply connections (grid) and electrical networks Planning of transformation stations up to 400 KV Air conditioning sizing of AC rectifiers and transforming stations Technical compression testing of buildings for energy supply Creation of licence documentation for power supply industry Devising of protective drafts Planning, production and implementation of small & medium wind & solarpower stations

11 PROFILE Planning & Consulting II Development of concepts for power supply systems including - grid solution - high voltage cable structure and dimension - examination and optimization cable losses and performance - fiber optic solution Grid short circuit calculation Grid load flow calculation Development of concepts for power supply systems including necessary documentation for transfer points up to 36 KV and power stations up to 400 KV Development of wiring manuals Creation of technical tenders Development of concepts for protection and timetables for staggering Development of concepts for monitoring systems Development of concepts for green energy solutions with windmills and solar systems OFF or ON grid solution

12 CHALLENGES & SOLUTIONS Starting situation: Effects of the increasing feed-in from regenerative energies on the grid Temporary imbalance between fed-in and consumed active power increasing requirements regarding controlling energy (primary and secondary control, minutes reserve, P(f)-behavior) Stochastical feeding from regenerative energy sources load- and voltage fluctuations in the supplying power system Influence on the systeme voltage and current during network faults Grid and grid protection is not dimensioned and parameterised for decentral energy generation Management / regimentation of the generated active power Participation in network control Support of the network voltage during faults Delivering of short circuit currents Dynamic and stationary reactive power delivery Behavior like a conventional power plant! Transmission system operators demands on PV & wind power plants

13 CHALLENGES & SOLUTIONS Calculation of the stationary P-Q-behavior - Typical configuration of a Wind Power Plant grid - Coupling point to the transmission system (220, 380, 400 kv) Transformer 400 / 110 kv 110 kv 110-kV-cable 110-kV-cable 110-kV-cable Transformer 110 / 33 kv 33 kv kV-cable Transformer 110 / 33 kv Transformer 110 / 33 kv 33 kv 33 kv 33-kV-cable MS...
