Managing Distributive Transformers

The power companies are aiming for the more cost-effective delivery of high-quality electrical energy. In order to increase the economy and the quality of the electricity supply, it is necessary to connect the substations to the system by means of which remote control and management of substations are carried out. The paper presents the solutions of communication paths, introduction of transformer stations into the remote control system. By designing the remote control system, voltage and load capacity measurements are provided, as well as signaling of the failure current. Thus, the automation and optimization of the key parameters of the substation is achieved. For less complex distribution substations, the classic solution that includes a SCADA cell computer with a monitor workstation will be replaced by a simple device designed as a communications control device. It can be concluded that the communication control device, the CCU without display, is the optimal solution. Remote monitoring and management significantly reduces interruptions in electricity supply as well as maintenance costs, and rapid adaptation to variable production and consumption is achieved. In view of the above, the need for remote-controlled secondary substations is inevitable.
