Control systems for fired turbine and diesel generator power stations

Control systems for 125 MW fired turbine power plant, two AOY-1.6AA fired turbine power plants, and a four-unit diesel-generator power station 4?1.2 MW implemented by Neva Electric Open JSC are considered.

Kiselyov S.K., Romanova E.V. The algorithmization technology for instrument calibration automation systems

The paper discusses the problems of algorithms development for automation systems used in instruments calibration. It offers a technology for adjusting the calibration automation system to new instrument types. The technology is based on the learning of an artificial neuron network, which underlies the system algorithmization.

Industrial Ethernet – the most popular industrial bus of 2003

Based on 2003 results and the forecast up to 2006, the paper shows that Ethernet became the most frequently used fieldbus. It notes that Klinkmann in cooperation with Wonderware, Unitronics and Hirschmann has developed a concept of industrial Ethernet application to process automation and reports preparation. It finally presents a range of Hirschmann’s equipment intended for Ethernet applications, and a new Unitronics Vision 2xx PLC with an Ethernet interface.
