This article considers power supply of consumers in the Far North. It is proposed to use systems which include units operating on liquefied natural gas and hydrogen. Such units have a number of advantages over the currently used diesel power plants. The main advantage is a significant reduction of emissions to air and environmental pollution. The use of gas turbine units, comprising a turbine and a highspeed generator, also allows one to reduce the weight and dimensions of the power plant. The issues of choosing the structure of the power supply system for the given operating conditions are considered: the basic requirements are formulated and a list of quality indicators of the system functioning is determined.

Power supply systems for small businesses based on renewable energy sources are most often based on converting wind energy, solar energy and water energy. Calculating its effectiveness is a time-consuming task, requiring the processing of a large amount of data specific for the geographical location of power generating units. In the article the technique of computer modeling of work of a park of wind power plants (WPP) with the purpose of definition of an optimum parity of their parameters is considered.

Special Meaning

The article considers the features of design of industrial power supply system of metallurgical enterprises with on-site electrical power generation. The problems of increasing the efficiency of the main electrical equipment of on-site power plants are formulated. The analysis of development trends in the energy sector of Russian metallurgy is carried out, on the basis of which the importance of industrial on-site power plants is shown. The problem of choosing a generator automatic excitation control system of on-site power plants is con-sidered and possible ways of its solution are given. The task of regime optimization of industrial on-site power plants is considered and original optimization algorithms are presented. Methods of increasing the reliability of power supply of critical equipment and mechanisms involved in the technological process of thermal power plants are proposed. The urgency of the tasks of complex automation and digitalization in the industrial power supply systems is shown, while the special meaning of "digital twins" is noted. Possible prospects for the development of on-site power plants in the context of the decarbonization policy and the transition to alternative energy are considered.

The purpose of the study is to analyze the prospects for the development of loading methods for gas turbines as well as to develop a mathematical model that adequately describes the real operating conditions of the loading system at various loads and rotation speeds. A comparative analysis of the most common methods and technical means of loading the shafts of a free turbine at gas turbine plants intended for operation as part of gas pumping units is presented. Based on the results of the analysis, the expediency of using the loading model “Free Power Turbine Rotor–Hydraulic Brake” as a load simulation is shown. Recommendations for the creation of an automation system for the load testing of power plants have been developed. Mathematical models and Hardware-in-the-Loop simulation models of power plants have been developed and tested. One of the most important factors that predetermine the effectiveness of the loading principle is the possibility of software implementation of the loading means using software control systems that provide the specified loading parameters of the gas turbine.

In 1996, Cogeneration-Kraftwerke Management Steiermark (CMST), OMV Cogeneration, together with local partners, built a 25Mwel gas turbine plant with a hot water boiler for thermal energy to be used by a car manufacturer and the municipality Graz, Austria. The plant is driven by a FT8-30 (JT8D-219) Pratt & Whitney (P&W) jet engine, accumulating 8200 operating hours per annum. This paper outlines the technical experience and related problems with the existing equipment in the light of variable operating conditions and the investments for efficiency augmentation of the gas turbine trains. A joint-venture between Cogeneration Kraftwerke Management Obero¨sterreich GmbH (CMOO¨) and OMV Cogeneration GmbH as well as Energie AG. CMOO¨ has operated the Combined Heat Power CHP Plant (50 MW el) in the paper mill SCA GRAPHIC LAAKIRCHEN based on contracting since 1994. Because of a extension of the paper mill the energy supply had to be increased. So the delivery of two steam boilers with each 30 t steam per hour and water treatment took place in August 2001. The plant-extension will operate as an independent unit and will guarantee the full availability of the energy supply. Commercial operation will start in January 2002.

Effective Integration

The capture and sequestration of the CO2 emitted from fossil-fuelled power plants is gaining widespread interest for controlling anthropogenic emissions of greenhouse gases. Among technology options for CO2 capture, membrane-based gas separation systems are noteworthy owing to their low energy requirements, promising technology evolution and effective integration with power plants. This paper presents a mathematical model for membrane-based separation systems that is able to cover the most significant membrane types and configurations. This model has been integrated in a general simulation method for analysing and optimizing advanced energy conversion systems. Performance of these simulation tools is demonstrated by evaluating the influence of different operating conditions on the behaviour of pre-and post-combustion separation units, based on metallic or polymeric membranes. Finally, the feasibility of integrating a metallic membrane system into a chemically recuperated gas turbine (CRGT) power plant is explored, obtaining encouraging results for CO2 capture.
