FSC Dayton, SVC Porter/Ninemile

Three protocol converters were supplied for this project.

The protocol converters for SVC Porter and SVC Ninemile link the redundant SIMATIC TDC control system to the control station. The protocol converter and the control station communicate via DNP 3.0. Data transmission in the direction of SIMACTIC TDC is based on the proprietary Simatic TDC and  TDC-X protocol.
The TDC-X protocol is used to send commands to the connected external devices via the control station, enabling SIMATIC TDC to assume control of the external devices.
In order to pass the TDC commands to the control station, the TDC-X/Slave (protocol converter) translates these commands into indications. Then the DNP/Slave (protocol converter) dispatches them to the DNP/Master (control station).

A third protocol converter for FSC Dayton allows linking the Simadyn D control system to the control station.


Three Siemens Flexible AC Transmission Systems (FACTS), two Static VAR Compensators (SVC) and one Fixed Series Capacitor (FSC) were supplied to realize this project. The FACTS are located at the three Entergy substations in Texas and Louisiana.
The project's goal is to make the power network more reliable, increase its capacity and to assure supply availability for the growing demand of of Entergy's Western service area. Another goal was to increase network stability.

Entergy has delivered energy to its customers in Arkansas, Louisiana, Mississipi and Texas since the beginning of the 20th century. In 2003, it served about 2.7 million customers.
Entergy owns and operates power stations with a total capacity of about 30,000 MW, it is the second largest US nuclear operator.
