Dispatching service of JSC "Network Company" is designed to provide: continuity and reliability of the power system, power distribution in accordance with the of load schedule, support for the established power system parameters (voltage, frequency in the electric system, etc.), the maximum efficiency of the power system as a result of the optimal use of different energy sources. Any changes in operating conditions and the condition of the power system components are to be displayed in a convenient form for the manager. Today, control panels are the most common devices of large-scale schemes displaying in a holistic way. With their help, the dispatcher controls and coordinates the joint work of several electricity networks in a single grid. Information on the state of the power system and its constituent subsystems is collected, recorded, processed and displayed by automated systems. This problem was successfully solved by modern control systems of "KER-Engineering", included in the program technical complex "ACSD": "ACSD AKP", "ACSD AAP", "ACSD ADS." With a multi-structure, PTC "ACSD" provides high availability and scalability for future upgrades. The versatility of PTC "ACSD" allows for the collection, processing, storage and transmission of information, along with providing time synchronization with the low-level devices.
