Abstract
The development of technologies in the world has played a big role in the improvement of energy management. The level of development of electric energy has a great influence on the dynamics and arrangement of the country’s productive forces, creating a necessary prerequisite for raising the standard of living of the population and improving working conditions. The level of the national economy and the energy supply of the population largely depends on the energy industry. Its development rates and scales have a decisive influence on the final results of the country’s economic development.
Supervisory Control and Data Acquisition (SCADA) is an important and relevant component of the electric power industry, which provides real-time monitoring and management of electricity production, transmission and distribution. The main purpose of the SCADA system is the management and operation of technological automated processes. SCADA system includes hardware and software components. The equipment collects data from the transformers on the power plant and provides them to the field controllers, which in turn transmit the data to the first and second level systems, And they, in turn, process and display information through a corresponding graphical interface on the video wall or at the operator’s workstation. SCADA systems also record the status and corresponding changes of all processes occurring in the power system. The control functions of the SCADA system ensure remote monitoring and management of the power plant and substation by the dispatcher, sending the necessary parameters from the control panel to the devices and relays in the station, to carry out data collection and their analysis for management decisions. “Georgian State Electrosystem” is one of the leading companies in the implementation of modern information systems. The function of GSE is to maintain system stability and reliability in both short and long term periods. There was implemented in GSE the project of updating software and hardware components of Supervisory Control and Data Acquisition system on the basis of SINAUT SPECTRUM 7 (SIEMENS), which was due to the rapid development of the electrical network, what followed was the addition of new energy facilities to the system and the correspondingly increased amount of incoming data. The old hardware was not designed for a such large load and therefore caused overloading of servers/hardware, which, in turn, was a hindering factor for efective dispatch management and control. Within the framework of the scientific research, the significance of the installation of the SCADA system in the electric power industry and the analysis of its development stages were highlighted. The introduction of the SCADA system contributed to the development of dispatch management and control, which reduced the number of technological accidents and made the energy sector stable in Georgia. The introduction of the substation management system ensured full local control of the substations. The software and hardware upgrade of the SCADA system facilitated complete remote monitoring and management of power stations and substations.
Based on the above scientific research, the following recommendations were developed: • In the Automatic Generation Control module of the SCADA system in Georgian State Electrosystem, it is recommended to integrate several regulatory power plants, which will ensure the stability of the power system, increase overflow control, add more stability and reduce electricity overflow losses; • For the stable functioning of dispatch management and control, it is recommended to establish a backup dispatch center, which will be located at a remote location and will work in parallel with the central dispatch center. Accordingly, in the event of faults in the communication network of the SCADA system, there will be no complete loss of access to energy facilities, which will add more stability to the electric energy of Georgia and prevent the occurrence of emergency situations. • It is recommended to widely implement energy saving systems, through which it is possible to control the imbalance of electricity. If the mentioned recommendations are taken into consideration, the energy system of Georgia will become stable and efective. This scientific research will be useful for the energy companies where the SCADA system is introduced or implemented.
