PROJECT OF INCREASING THE RELIABILITY OF POWER SUPPLY TO THE CITY OF ASHGABAT

 

         Great works was completed to increase the energy supply of the capital of Turkmenistan, Ashgabat. In accordance with the Resolution of the President of Turkmenistan in 2012-2014, a number of energy facilities were built and put into operation in three stages that ensure a uniform distribution of electricity, maintaining its voltage and frequency at an appropriate level. Within the framework of this project, the Paytag dispatch center of the Ashgabatenergo Production Association and modern transformer substations, including 5 substations with a voltage of 220 kilovolts, 22 substations with a voltage of 110 kilovolts and 29 substations with a voltage of 35 kilovolts, have been constructed. 140 transformer and distribution substations with a voltage of 10 kilovolts have also been built. In addition, air and cable power lines were laid, the total length of which was respectively 83.2 and 785.1 km. All substations are equipped with specialized modern equipment and advanced technologies from such world leading companies as General Electric, Schneider, Siemens, Alstom and others, including video surveillance systems and electric meters installed in the control center. These projects were prepared and implemented also taking into account such a factor as the combination of new buildings with the architectural appearance of the white marble Ashgabat.

In the Paytag dispatch center of the Ashgabatenergo Production Association, built in the framework of the project to improve the reliability of the power supply of the capital, the most modern high-tech equipment was installed and all the necessary conditions for the successful work of the staff were created. This is an original two-story building in its architectural embodiment in a residential area in the center of the capital. On the first floor there is a dispatcher room, from where the entire power system of Ashgabat is controlled, which is schematically displayed on the large monitor installed here. All relevant information and video images are transmitted over fiber-optic cable lines.

The SCADA system (supervisory control and management system) makes it possible to monitor the control of all incoming data from substations with any of them. The dispatch control centers are designed to effectively eliminate possible problems in the power system that may arise in conditions of medium and high level of power consumption, as well as to automatically switch areas, for some reason temporarily without electricity, to power from other substations for the purpose of rapid and High-quality power supply to consumers.

One of the advantages of the control room is the ability to remotely switch on and off equipment and power lines. Based on the analysis of the information received, a decision is taken to continue the work or to carry out the necessary preventive or repair measures. The new dispatch center is an integral part and at the same time the final and managing segment of the improved power supply infrastructure of the city of Ashgabat. Another of its features is the possibility of parallel operation with the Central Dispatch Office of the Ministry of Energy of Turkmenistan.

Commissioning of this center made it possible to carry out a precise control over the stable functioning of the energy system in Ashgabat, efficiently manage electricity flows, coordinate electrical repair operations as necessary, and ensure the proper operation of uninterrupted power facilities.
