Problems of construction of automated electric power supply control systems (APSCS) are relevant for the oil and gas industry. There are articles devoted to the problems of formulation, formalization and algorithmization of separate functional tasks of APSCS. A number of issues related to the interaction of APSCS components with the primary measurement devices and process-specific information and measuring systems, remains unresolved. The essential difference of APSCS from process ACS is the low inertia of the electromagnetic and electromechanical processes. As part of supply voltage monitoring problem solution to meet the quality control requirements of electrical energy requires a high sampling rate of the input signals. Obtained scopes of data are too large for processing and long term storage. Capabilities of existing process- specific measuring systems are not sufficient to meet these challenges. The problem of creation of high-precision, non-filled at alarms primary sensors for APSCS is not solved yet. Creation of information and measuring systems for APSCS may be possible either on the basis of modern industrial computers with large processing power and high-speed solid-state hard drive, or on the basis of modern industrial microcontrollers. The main difficulty is related to the requirement of high-precision synchronization of measurements, in the long term the application of radio frequency signals of GLONASS/GPS satellite systems or fibre-optic cables is possible. However, the solution to the problem of APSCS information support does not resolve the problem of their performance, which is not enough to work in real time. APSCS should solve the problems of decision-making support in the field of industrial electrical engineering systems (EES) control. One of the pressing issues of the reliability improvement of EES is also the decrease of abnormal operation probability of emergency shut-down and automation systems. The probability of abnormal operation of microprocessing protection exceeds manifold the same value for the systems based on electromechanical electronic components. The algorithmic solution of the problem is proposed. Algorithms should be based on a simple physical sound relations between monitored parameters of the electrical engineering system. The functionality of standard measuring and control means is enough to solve this problem. A number of examples is considered for reliable diagnosis provision for emergency disturbances. It is proposed to solve this problem by the creation of automatic control for electric load units that will improve the reliability of liquidation of EES emergency modes and reduce the number of false and unjustified trips.
