MEASURING INDICATORS OF ENERGY PROCESSES IN THE ASYNCHRONOUS GENERATOR ON THE BASIS OF THE VIRTUAL MODEL IN THE LABVIEW SOFTWARE
Journal Title: Електромеханічні і енергозберігаючі системи - Year 2017, Vol 2, Issue 38
Abstract
Purpose. To investigate the process of power generation in the autonomous sources of energy based on an asynchronous generator with capacitive excitation and creating easy to use and clearly virtual device performance power modes. Methodology. Mathematical tools used method based on instantaneous power spectral analysis of electrical signals, allowing maximum clearly to display process generation and energy recovery between the power source and consumer of electricity. In work presents a virtual laboratory complex for the research of autonomous power supplies based on diesel generator sets, consisting of a source of mechanical energy - a diesel engine, source of electric energy - an asynchronous generator with capacitive self-excitation, and a typical consumers of electrical energy. The complex contains a meter of energy conversion indicators, which allows to visualize the processes of energy conversion, transmission and consumption. Results. An algorithm for measuring the quality and quantity of energy conversion in the "asynchronous generator-consumer" circle was developed, which is based on the instantaneous power method. Originality. For the first time used a method based on instantaneous power spectral analysis of the electrical signals to determine the quality indicators of energy conversion. The presented electric power conversion indicators for DC motor power supply, are connected to the terminals of the asynchronous generator using a rectifier. Practical value. Energetic processes makes it possible to assess the quality of energy conversion and subsequent analysis of ways to improve the energy efficiency of autonomous energy sources.
