This year’s in-house exhibition will be held on May 28 and 29 in Ettlingen. Speakers from IDS and from other companies will present plenum speeches on the changing energy market and the resulting requirements on IT and automation solutions.

Furthermore, there will be papers on solutions for efficiency enhancement, cost reduction and reporting duties, as part of the discussion of incentive-based regulations and new product developments, in the fields of telecontrol and SCADA engineering. This will be rounded off by an exhibition of IDS products.

The evening entertainment will give participants a taste of the local wine region. A detailed program, together with the official invitation, will be posted to customers and interested parties at the beginning of April. We are looking forward to welcoming you to Ettlingen!

The new release 1.5 of the ACOS ET engineering tool enables the parameterisation of communication links on the basis of the IEC 61850 standard.

This means that RTUs of the IDS 850 and IDS 650 series can be used e.g. as gateways between the station bus acc. to IEC 61850, and the telecontrol protocols acc. to IEC 60870-5-101 and -104.

Apart from ist application as communication protocol for protection and control equipment in electrical switchgear, the IEC 61850 standard is by now also being used as the basis for communication for the operation and monitoring of hydropower plants (IEC 62344), wind power stations (IEC 61400-25) and installations for decentralised energy production (IEC 61850-7-420).

The IEC 61850 does not only standardise the actual data transmission procedure, but also the engineering data required fort he parameterisation fo communication links. ACOS ET supports all engineering steps and data specified by the standard, by means of the integrated engineering tool SCT. This includes, but is not limited to, the IEC 61850 system engineering with the possibility to import/export SCL/SSD files; the IEC 61850 device configuration with the possibility to import/export SCL/ICD files; and the IEC 61850 system and device parameterisation based on SCL/SCD files.

Vattenfall Europe is one of Germany’s leading energy supply companies. Vattenfall’s activities include the mining and electrification of cheap German lignite, the generation of electrical energy through hydropower, anthracite and nuclear power plants, as well as the transport, distribution and trading of energy.

As Europe’s fourth-largest producers of electricity and largest producer of heat, Vattenfall Energie caters for ca. six million customers all over Europe. In 2007, a total of 167.7 TWh of electricity and 36.2 TWh of heating was generated and distributed.

Vattenfall Europe supplies electricity and heating to the City of Hamburg in north Germany, and electricity  to the West Mecklenburg region in the north-eastern part of Germany. Hamburg’s power grid covers a total of over 7,000 km, that of West Mecklenburg more than 6,000 km. The annual electricity output via the power grid amounts to more than 15,000 GWh.

IDS GmbH is commissioned by Vattenfall Europe Distribution Hamburg GmbH to install a highly-available IDS HIGH-LEIT XW SCADA system for the operation and monitoring of the two distribution networks of Hamburg and West Mecklenburg via the control centre in Hamburg.

An extra challenge to the flexibility and engineering of the SCADA system’s functionalities was the integration of two grids with different structures into a uniform alarm and operator control system.

The new SCADA system will be distributed to two locations which will be connected by means of a redundant FO link. The process interface is based on eight redundant frontend computers, type IDS 850, which will be distributed to two locations in Hamburg and one in Schwerin. The SCADA system will be used fort he operation and monitoring of eight 380kV transformer stations, ca. 100 110kV transformer stations and of 46 20kV switchgear stations.

Apart from the well-proven image processor for the visualisation of the different installations and of ca. 11,0000 transformer stations and switchgear stations via world map, the SCADA system also features an intelligent topology processor and a grid calculation kernel. The latter supports the operator by providing online short-circuit current and load flow calculation, e.g. for switching operations.

In addition to online computers, the system will also include a training and instruction system which can be used to emulate fault scenarios both in the high- and medium-voltage grid.
