Opis:: During a blackout, after the post-disaster collapse of an electric power system (EPS), units of thermal power plants should switch-over to the house load operation mode (PPW). However, regarding the dynamics of a post-disaster blackout process, many units can be in forced outage Therefore, restart of these units from the start-up sources with a self-start capability is necessary. The Transmission Network Code in force imposes periodic tests and system tests for such sources. Any system test must be preceded and followed by simulation investigations in which the possibilities: (1) to bring voltage to the started-up power plant by a starting path and (2) to activate the highest-power auxiliaries (PW) of the unit being started-up are evaluated. In the paper, chosen results of simulative investigations of the transient phenomena in the starting path from the hydroelectric power plant of Włocławek (HPP Włocławek) to the thermal power plant of Pątnów (w (TPP Pątnów), related to the system test conducted in September 2017 have been presented.

Opis:: In the near future the city of Opole, as well as the whole Opole Voivodship are going to suffer from a serious problem connected with the traffic system which provides for closing of the core bridge crossing from one part of the city to another one – the Ulga canal. The condition of the bridge crossing at Niemodlińska Street is constantly deteriorating. After the first expertise had been conducted by a construction supervision, the decision to close the bridge on 1st June 2015 was made. The decision is justified by the safety reasons and disastrous technical state of the bridge crossing. In order to delay the moment of the closing and lighten the bridge, the inside lanes were changed into bus lanes and thereby the centre of gravity has been moved closer to the bridge crossing axis. Cars are going to use outside lanes. In front of the bridge vehicles height limiters were set in order to eliminate trucks from the traffic. For this kind of vehicles a special detour was created (Wrocławska Street, Road No 45). After this procedure the next expertise of construction supervision was conducted whereby the exclusion of the bridge from the traffic was delayed for one year. For the time being, it is known that the third expertise is being prepared. During the bridge renovation the car drivers and public transport passengers who travel to work every day are going to come across the serious communication problem.
