The object of analysis is the life cycle of innovation TRIZ project, which is a «vortex», con-sisting of four consequent types of projects: exploratory, verificatory, innovative proper and the implementation project. In exploratory projects the search for ideas is performed as well as the evaluation of their potential economic efficiency, influence upon business, technical implement ability (contradictions are identified and resolved), presence of market and potential applicability for creating innovations. Conceptual trends are developed. Further on, the concepts are developed and the benchmarking of these concepts is carried out. In verificatory projects the actual check of implement ability of technical solutions is carried out within the frames, proposed at the preceding stage of leading concepts, secondary problems are identified and the solutions for solving them are developed, specification of their economic evaluations is carried out, market perspectives are evaluated and potential Customers are identified. As a result, leading verified concepts are identified, which are most applicable for creating innovations. In an innovative verified concepts are optimized until a new product and technology is created and based on them the model of new business is developed (or already existing business is substantially modified). And finally, the implementation project presupposes the implementation of developed innovations in the actual business. Milestones and stages of project types is described, typical benchmarks for milestones and stages are established. A two-level verification pattern is proposed. Also, the basic principles for controlling the portfolio of innovation TRIZ-projects.

In the modern world, where environmental problems are becoming increasingly urgent and the cost of traditional energy carriers continues to rise, the development of wind generators is gaining particular importance. One of the promising directions is wind energy, which is especially attractive due to its accessibility and efficiency. This article examines the possibility of creating an autonomous power supply system based on a wind generator made from an electric bicycle hub motor. The technical characteristics of the developed installation are presented, and the economic efficiency and payback period of the project are calculated for the conditions of the Arctic region of the Republic of Sakha (Yakutia). It is established that the estimated payback period is 14 months, which confirms the economic feasibility of applying this solution in remote and decentralized areas.

The electric power industry is critical to the economy, yet it faces significant challenges: much of the infrastructure, particularly electrical grids and major substations, is significantly deteriorated or overloaded. This is particularly true for electrical substations, where highly loaded equipment has reached the end of its service life, increasing the risk of failures and process accidents. This article examines the need for equipment modernization at the 220 kV Tommot substation. The objective of this project is to replace the existing outdated and overloaded 16 MVA T-3 and T-4 power transformers with more powerful ones. The study presents a comprehensive analysis of the substation's current condition, including its geographic location, technical characteristics, and load parameters, based on control measurements. It also examines the theoretical foundations of transformer operation, their classification, and key characteristics to justify the selection of new equipment. Short-circuit current calculations were performed to verify compliance.
