Abstract: Показано, что известные устройства и терминалы релейной защиты и автоматики (РЗиА) возможно заменить обобщенной эквивалентной структурной схемой двухвходового устройства. Такая упрощающая абстракция позволяет эффективно решать задачи анализа, синтеза, оптимизации, совершенствования, унификации, обучения и др. в области РЗиА. Абстракция помогает оперировать потоками информации во множестве связанных объектов управления и защиты, к которым сводятся участки электрических сетей разных классов напряжений для традиционных и смарт-грид построений. Двухвходовое, а в пределе одновходовое устройство, является многопараметрическим обработчиком потока информации и относится к области технического интеллекта. Приводится описание структурно-информационного метода, на основе которого получена предлагаемая абстракция.
Description: Combination of many factors: expansions of multi-criteria terminals of Relay Protection and Automatics (RPA), building smart-grid electrical networks, problems of RPA solving for specific objects of control and protection (OCP) showed the necessity to operate by the information flows to a higher abstract level with reservation the information about OCP and RPA in the description. OCP groups in power industry usually work together and are connected energetically, galvanically and informationally. In this regard, there is possibility to allocate a separate type of OCP - array of associated OCP (AAOCP). It is shown in the paper that the well-known devices and terminals of RPA can be replaced by a generalized equivalent structural circuit (GEC) of two-input device. GEC device consists of two elements: generalized filter and threshold umt. This simplifying abstraction gives possibility to effectively solve problems of the analysis, synthesis, optimization, development, standardization, traimng, etc. of RPA. Abstraction helps to operate with the information flows in AAOCP where the parts of electrical networks of various voltage classes of traditional and smart grid constructions are thrown together. Two-terrninal, and in the lin1it one-terminal GEC-device, is a multi-parameter processor of the information flow and relates to the field of technical intellect. A structure-information (SI) method is described in the paper. On the basis of this method the proposed abstraction is obtained. A theoretical basis of SI method and evidence of its effectiveness are developed. SI method involves structural-operator, structural-linguistic and structural-l1ierarcl1ical methods. SI-method is umversal and can perform various tasks related to the analysis, synthesis and control of the flow of sense situations in the research object. In this paper one more element of SI method’s theoretical basis, rationale of use of GEC device, is developed. According to SI method, a generalized tree, for recognition of known schemes the balanced discriminators and detectors, is made. Grammar, a list of rules "Yes-No" are compiled. Grammar allows the study the quality of the well-known devices, the devices under development and RPA systems. The hierarchical line of solutions design of discriminators from "simple" to "perfect" is built. The line enables to perform qualitative and quantitative evaluations of the effectiveness of RPA devices and count indicators of developed RPA devices. Relative action device, balanced discriminator or phase detector (PD), is in the basis of the evolution line of RPA devices. In this case absolute action device of RPA are simplification of GEC device.The proposed in the article smart detector "Yes-No" turns the most perfect". Joint-work of GEC device and AAOCP in the unified intellectual smart grid automatic control system is discussed. The examples of structural circuits of smart control systems in the smart-grid electric networks are presented.
