Abstract
This article describes rules and conditions for making a structure (a set) of facts for an expert knowledge base of the intelligent system to diagnose Wind Power Plants’ equipment. Considering particular operational conditions of a technical object, that is a set of Wind Power Plant's equipment, this is a significant issue. A structural model of Wind Power Plant's equipment is developed. Based on that, a functional – diagnostic model of Wind Power Plant's equipment is elaborated. That model is a basis for determining primary elements of the object structure, as well as for interpreting a set of diagnostic signals and their reference signals. The key content of this paper is a description of rules for building of facts on the basis of developed analytical dependence. According to facts, their dependence is described by rules for transferring of a set of pieces of diagnostic information into a specific set of facts. The article consists of four chapters that concern particular issues on the subject.

This paper aims at developing a set of rules for a knowledge base of the expert system that will allow identifying defects of the object under examination
A designed knowledge base relates to the (WPP) consisting of five (5) unit (WTGs) of type Vestas V90 2.0 MW connected to the (HV) Substation by means of two 20-kV cable lines, which are an internal Electrical Infrastructure of the Wind Power Plant (Fig. 1)
Summary
Expert systems are programs that can help or replace human experts in a specific field. Waterman and others in this issue since their works [4,5,14,15,16,17,18,19] cover mathematical background in terms of development and organization of expert systems, including rules for creation of expert knowledge bases, creation of conclusion rules and means of their analyses (look through and sort out). The author presented mathematical basis of the policy rules of the organization of repairs (replacement of components (constructional elements)) of devices Another important practical problem which was solved in the study is the representation of the ways and methods to set periods of repairs (replacements of functional parts) of devices and their optimization. This paper aims at developing a set of rules for a knowledge base of the expert system that will allow identifying defects of the object under examination
