10 September 2003 - Siemens Power Transmission and Distribution (PTD), Erlangen, Germany, has received from the Kazakhstan Electricity Grid Operation Company (KEGOC) an order to modernize the control and protection equipment in all its substations. The order is worth more than €50m ($56m); it is the largest individual order received so far by the Power Automation Division.
The aim is to improve the reliability of energy transmission and also the availability of the electrical grid. Siemens PTD will replace the existing equipment of 67 high and extra-high-voltage substations in Kazakhstan with state-of-the-art control and protection systems. The scope of performance includes not only the supply of hardware and software, but also engineering, commissioning and training of operating and control room staff.
In this modernization project, Siemens will replace all the existing analog solid-state protection devices in the substations with digital systems from its Siprotec product line. Additionally Siemens' substation automation system Sicam will be supplied. Sicam and Siprotec components constitute a uniform solution for control and monitoring of the power transmission and distribution systems. In the substation control rooms the conventional control panels will be replaced by modern display workstations for the operators. The ease of use of the system components, it's electromagnetic insensitivity, it's long service life and ability to provide operating and diagnostics data were crucial factors for KEGOC's decision to choose Siemens substation control and protection technology.
This is the largest single order received so far by the Siemens PTD Division Power Automation. Division President Andreas Matthé comments: "With this project in Kazakhstan, we have a significant opportunity to demonstrate our leading-edge expertise in the automation of power systems. I am convinced that neighboring countries in this region will take notice."
The Kazakhstan Electricity Grid Operating Company (KEGOC), Almaty, a state owned company, runs the national high and extra-high-voltage network (from 110 kV to 1,150 kV), along with the associated switchgear and substations. The corporate assets include 110 kV to 1,150 kV transmission lines and master substations forming the national power grid that provides interstate flows and power supply from power plants connected to the regional power network companies and major customers. In addition to network management in Kazakhstan's liberalized energy market, KEGOC is also responsible for exchanging power with neighboring countries. Total length of common transmission lines of the republic amounts to about 338 000 km. Further Information: www.kegoc.kz.
