Abstract The maximum instantaneous power consumption of robot drives determines the requirements for the energy supply system and the dimensions of the machine. For numerous machines, there are no technological restrictions on the types of applied motion laws and their numerical characteristics i.e. maximum speeds and accelerations. The type of the motion law and especially its parameters are traditionally determined according to the preferences of the design engineer without any justification, though some-times restrictions on maximum accelerations or speeds are considered. The restrictions on maximum accelerations are related to ensuring the strength and accuracy of the drive, and the restrictions on maximum speeds are related to the safety of personnel in the workplace. The motor power is selected according to the maximum value of the instantaneous power and thermal load, which depends on the duration of switching on. The article analyzes the ways of minimizing of this maximum (peak) of instantaneous power inside the cycle for different laws and different loads. The main parameter by which the maximum (peak) power is minimized for all types of laws is the acceleration and braking times. On the example of the most common motion laws, the dependence of instantaneous power and energy consumption on accelerating time and braking time for various types of loads are studied. In this article, the dependence of instantaneous power and energy consumption on accelerating time and braking time for various types of loads are studied on the example of the most common motion laws. The research results are intended to create a design technique for drives of modern equipment.

The Impact

Nowadays the issue of electric energy saving in public transport is becoming a key area of interest, which is connected both with a growth in environmental awareness of the society and an increase in the prices of fuel and electricity. It can be achieved by reducing of the transmission losses in supply system or by the improving of the usage of the regenerative breaking. The spatial differentiation of the energy supply system of public transport is one of the elements, which has significant impact on the energy consumption. Paper presents the theoretical analysis of the impact of supply system topology on the energy consumption and extensive measurement analysis realized in Gdynia (Poland) trolleybus system.

More and more countries are focusing on the lack of resources with the consumption of large quantities of fossil energy. The Chinese government is actively promoting the policies related to the transformation of the energy structure which will increase the proportion of clean energy consumption and reduce the proportion of fossil energy consumption in order to relieve the pressure on domestic energy. Interest in the generation of biogas from agricultural residues is increasing rapidly due to its climate benefits. This article is committed to analysis the economic performance of the biogas cogeneration energy supply system of livestock and poultry breeding plants in southern China. The model of the biogas cogeneration energy supply system of livestock and poultry breeding plants in southern China and the advices to the government will also been proposed as a result. According to the results, biogas cogeneration system is feasible in economy with reasonable device configuration and operating strategy.

Topological Models

In the design and operation of energy intensive systems, the possibility of improving the system’s efficiency is very important to explore. The main way of improving efficiency is through optimisation. This paper describes the application of exergy topological models and, in particular, the graph of thermoeconomical expenditure for thermoeconomical optimal design s of circled nets for energy supply (CNES). The questions of thermoeconomical optimisation of CNES, as well as suggested modelling algorithms, are illustrated in the numerical example of the optimisation of a energy supply system for a city with seven regions of energy consumption.
