ETIP

By the use of renewable energies and the decentralization of electricity generators a dramatical change in electrical energy grids is taking place. This leads to a new supply system layout covered under the transition goal called Smart Grids. In Smart Grids new system requirements for automation, communication and power quality are provi-ded and have to be fulfilled. The major challenge is to establish a dynamic control function like primary and secondary controller of conventional power plants and grids from the TSO level into the low and medium voltage grid level (DSO level). These kinds of functionalities must be implemented into the power electronic inverters and into the control function of decentralized synchronous generators as well. Additionally, the automation system for the DSO level has to be adapted to these new require-ments. The substation automation must be fitted into these new grid control functionalities. Therefore the demand for new Smart Grid orientated solutions which are flexible, adaptive, sustainable and cost effective are obvious.

EnTeSys develops and offers innovative technologies to advance the integration of distributed, renewable power supply systems. The focus is on how these decentralized systems can coexist with conventional power plants. EnTeSys developed a strategy to fulfill the complex requi-rements which electric energy supply systems of the future will have.

As a specialist for intelligent software solutions for smart grids, EnTeSys develops FPGA-based IP Cores for power system components. These Energy Technology IP Block-sets ETIP offer a platform for simple, fast and flexible FPGA based development for electronic devices in Smart System applications. The modular ETIP Blocksets are consequently designed related to the requirements of Smart Grids. ETIP Blocksets cover the different types of feeding modes and grid code from the TSO and DSO side. In terms of communication IP Cores for standard ITC technologies via Ethernet and fieldbuses are available (TCP/IP, EtherCAT, etc.). The ETIP Blocksets philosophy offers a wide range of application fields in Smart Grid devices. Starting from power electronic inverters, substati-on automation systems up to a direct PLC integration. The ETIP Blocksets cover all basic and major Smart Grid control and automation functionalities. The figure below shows in principle the wide application range of ETIP -based systems graphically.
