The motivation for this project is based on the fact, that present configuration of traction lines, old-fashioned trolleybuses and traction substations do not allow for the effective use of recovered energy. The fundamental issue lies in the transfer of recovered energy back from the DC traction to the AC distribution network. In many cases, this is not a technical problem on the side of traction substation only, but the reverse flow of the electrical energy can cause problems even in the distribution network. The distributor of electrical energy lays down restrictive conditions for allowing the reverse transfer of energy. With the latest developments in the field of electrochemical energy storage systems and particularly by continuously declining their prices, a modern approach aims to use stationary or mobile energy storage systems for saving non-utilized energy from the DC railway and to re-use it for covering the consumption peaks. We have verified options for long range control of energy flows between substations and trolleybuses. Based on the longterm on-site measurement and performed data analysis in our dedicated software we have defined critical points for significant energy savings. Now we can precisely define energy flow at the AC input of substations, in the DC traction and in the trolleybuses, themselves. Those analyses have been used as a proposal for the fundamental design of trolleybus’ onboard energy storage system.

- ItemPower plant steam superheater control system preliminary results and experiences from the field tests(STU, 2017-01-01) Hubka Lukáš; Školník Petr; Hlava JaroslavThis paper describes a newly developed steam superheater control system and its integration into the real power plant control system. The developed control system is based on the principles of the model predictive control. It is intended to replace one part of the existing classical control system that is based on gain scheduled PID controllers. The paper starts with a short description of the controlled plant and then it continues with the description of the predictive controller and its integration into the structure of the existing control system. The main focus is on the results of the functionality tests. The preliminary results hitherto achieved demonstrate the capability of the developed control system and its application potential. However, at the same time, they also show that extensive simulation testing of a controller for such a complex system does not necessarily guarantee perfect control performance and several modifications of the controller will be needed to make it really applicable.

- ItemTram simulation model for energy balance analyses(STU, 2017-01-01) Hubka Lukáš; Školník PetrThis paper describes a mathematical model of a tramcar which allows to simulate traffic on any tram track and allows to analyze energetic balance on the electrical power link without real energetic data measurement. The described mathematical model could be a useful tool for the design of an energy recovery system for a real tram track. A short description of the tram track model in the city of Liberec is presented together with the mathematical model of the tramcar type T3.PLF that operates on mentioned track. The model simulation results are confronted with data measured during the real tram operation.
