The modern trends of the electric power systems development intended to their modernization and efficiency improvement are associated with the development of both the technical and the processing facilities as well as the control models development. The industrial assets management systems are no exception. The present systems are intended to ensure the steady technical state control as well as the...
This article focuses on the question of the necessity and the amount of maintenance of protective relays and automation. It analyzes carefully current published works on this subject. In addition, the probabilistic model of protective relay's device state is constructed and applied here.
The relay protection and automation (RPA) is the essential part of the power system, which ensures the system failure-free operation. However, the inadequate attention is paid to the RPA operability problem during the electrical network reliability assessment. The study is focused on the determination of the RPA states probabilities with consideration of many factors characterizing the RPA ability...
The paper is concerned with the information and analytical systems for electrical grid equipment life cycle management at power stations and substations. The brief description of the modern information and analytical systems in electric power industry is presented. The data analysis and ranking procedure in the information and analytical system was developed for optimal equipment repairs program formation...
The solution of the secondary circuits effect consideration problem during electrical network calculation is presented in the paper. The analysis of statistical operational data concerning primary and secondary equipment failures taken directly from the plant was performed. It follows from the analysis results that relay protection and automation consideration during the reliability calculation is...
The paper is concerned with repair programs formation of the high voltage equipment at electric substations. The repairs strategy formation algorithm according to its technical state with consideration of its importance for power system is proposed. The proposed algorithm was verified in the context of 110 kV substation repairs analysis.
The paper presents the structure of decision support system for electrical grid equipment operation on the base of its state assessment based on aggregated available data concerning object of research by means of neuro fuzzy inference. Technical state assessment of both separate elements, notably electrical equipment (based on fuzzy logics methods) and integrated consolidated objects (by means of...
