“…As part of the configuration, the following are defined: the type of state logic and the range of their intervals; options for visual presentation in the state table; and RBF network parameters. The object states accepted for multi-valued logic were defined in Polish standards concerning the reliability and quality of service [6,[33][34][35][36][37][38][39] (Figures 8 and 9). Therefore, the classification stage in the diagnosis process determines a specific state for each basic element of the technical object examined.…”

This article presents the problem of diagnostic examination by the (DIAG) diagnostic system of devices of the House on Water (HoW) hybrid electric power system in the multi-valued (2, 3, and 4) state assessment. Forming the basis for the functioning of the (DIAG) diagnostic system is the measurement knowledge base of the object tested. For this purpose, the issues of building a diagnostic knowledge base for a hybrid power system for HoW are presented. The basis for obtaining diagnostic information for the measurement knowledge base is a functional and diagnostic analysis of the hybrid power system tested. The result of this analysis is a functional and diagnostic model of the research object. At the next stage of the work, on the basis of the model created, the sets of basic elements and the sets of measurement signals were determined together with the reference signals assigned. State classification in the (DIAG) system is based on an analysis of the value of the divergence metrics of the signal vectors tested. The purpose of the HoW diagnostic test is to assess an increase in the diagnoses developed by the intelligent diagnostic system (DIAG 2) in 4-valued logic in relation to the assessments in 3- and 2-valued logic.

“…Work [3] proposed, in order to simultaneously reduce the levels of voltage asymmetry and a coefficient of reactive po wer, to use specialized technical means -active symmetry-compensating devices (an analog to a three-phase active filter). The cited work showed that the reactive and asymmetrical components of current could be fully compensated for in such a device, even in the case of a distorted sinusoidality in the shape of the current and voltage curves.…”
