【 摘 要 】

The article shows the power quality indicators that are most important for electric consumers: high and low voltage, high-voltage pulses, harmonic distortion, unstable voltage, voltage dips. Possible contingencies in power supply systems of the ground complex (PSS GK) connected with a deviation from the norm of the quality of electric power parameters are analyzed. In accordance with this, the power quality indicators that affect the cyclogram of the preparation for the launch of a space rocket (SR), which need to be monitored, are determined. The objects of management of separate components for operational withdrawal from an emergency situation (ES) are considered. In order to improve the PSS structures and improve the quality and reliability of PSS GK, taking into account the operating modes, at the design stages of the power supply system of GK, it is necessary to create and allocate an automated remote control and monitoring system (ARKMS) as a separate structure within PSS NK. The main requirements for the ARKMS providing control of the power parameters at the terminals of the electrical consumers of the process equipment (PE) are determined by monitoring the oscillograms of the AC voltage, the voltage, frequency and the non-sinusoidal voltage of the alternating current voltage. In addition, ARKMS performs registration and display of power supply parameters of electric consumers, monitoring of the operation of PSS as a whole and their components with reference to a single-time system. In case of exceeding the permissible limits of the power quality indicators, ARKMS will allow to take operational measures necessary for parrying contingencies, thanks to the operation of the elements of the power supply system. Information support was provided with the construction of the generally accepted structural block diagram of such systems, on the basis of which the three-level structure of ARKMS is implemented. The algorithm and basic principles of the ARKMS operation in the normal mode and the mode of exceeding the norms of the power quality indicators (PQI) are considered. A brief description of the structure is given, as well as an example of an algorithm for input control of ARKMS.
