Mit der Erweiterung eines Produktionssystems um eine zusätzliche Produktionsanlage steht das Unternehmen vor der Frage, welche Energieströme zur Verfügung gestellt werden müssen und ob die Energieversorgung der Fabrik ausreichende Kapazitäten vorweisen kann. Dieser Beitrag stellt ein strukturiertes Vorgehen vor, wie diese Fragen aus energetischer Perspektive in einem frühen Planungsprozess adressiert werden können. Anhand der Methode werden die relevanten Rahmenbedingungen identifiziert und es wird aufgezeigt, welche Messdaten der Energieerzeuger nötig sind, um eine energetische Bewertung durchführen zu können.   Before including an additional production plant, a manufacturing company has to identify what energy flows need to be made available and whether the capacity of the factory‘s power supply system is sufficient. This paper presents a structured approach to address these issues from an energy perspective in an early planning process. This method helps to identify the factory framework and shows what measurement data are required to carry out an energetic evaluation of the available energy generators.

The problem of the non-sinusoidal modes analysis of the power supply system with non-linear elements and their influence on the efficiency of the power transmission are considered. It is carried out numerical analysis of electric energy flows for three phase power supply system with sinusoidal electromotive force source, linear active load and non-linear elements (diodes). Power transfer is considered as distribution of the primary power flow from source. The part of this flow is converted by non-linear elements and return into the network like secondary power stream of zero sequence and high harmonics which is consumed by resistance elements and causes additional power losses. As a result transporting efficiency and power factor are reduced and energy quality becomes worse. In order to improve the quality of electricity, it is proposed to normalize the relative value of the reactive power of distortion for non-linear electric collectors and to oblige manufacturers of electrical products to complete them with filters of higher harmonics. With the purpose of correct selection of the type and power of compensating devices and monitoring the parameters of the electric network mode, it is proposed to expand the functionality of electronic meters by dividing the reactive power into two components - shear power and distortion power, and for the objective analysis of energy flows, it is proposed to standardize the reactive power of distortion. It is shown that in such system current in neutral line increases due to overlaying of zero sequence harmonics currents. This should be taking into account during neutral line cross-section choice and power losses calculation.

Introduction: The co-authors provide an overview of the main types of wind turbines and power generators installed into wind energy devices, as well as advanced technological solutions. The co-authors have identified the principal strengths and weaknesses of existing wind power generators, if applied as alternative energy sources. The co-authors have proven the need to develop an algorithm for the selection of a wind generator-based autonomous power supply system in the course of designing windmill farms in Russia. Methods: The co-authors have analyzed several types of wind turbines and power generators. Results and discussions: The algorithm for the selection of a wind generator-based autonomous power supply system is presented as a first approximation. Conclusion: The emerging algorithm enables designers to develop an effective wind generator-based autonomous power supply system.
