Antismog tariff for electric heating and electromobility
Effective reduction of smog and its influence on human health and economy needs multiple threaded and coordinated activities targeted at elimination of its causes and formalised in the form of the National Program for Low Emission Elimination (KPLNE). The cause of smog situations occurrence is with no doubt the low emission of harmful substances resulting from combustion of low quality solid fuels and wastes in household stoves as well as the emission from motor vehicles. Using electric energy for heating residential buildings for which the supply of distric heating is not possible or economically inefficient, the application of gas or some other small-scale emission and permitted heating source will significantly contribute to reduction of the low emission level. Similar consequence will occur together with the rising amount of electric vehicles, replacing the motor ones, for which one must provide the charging infrastructure and an attractive offer for electric energy supply. The authors here present the concept to apply the electric energy for electric heating and electromobility as one of the tools postulated by KPLNE. An analysis is also made of the anti-smog tariff introduced in December 2017 with respect to its economic efficiency and ability of achieving the pursued aim as well as presented are potential directions of modifications. Shown are new solutions for electrification of heating sector and electromobility which arose as a result of cooperation and consultations between power industry trade unions, local authorities and scientific communities in 2017.

Hardware and software integration solutions of the DCS MASTER system in a turnkey object installations
In modernization works concerning object automation systems as well as in designing of new, complex systems in turnkey formula with participation of many sub-contractors, there is a problem of integration of many elements into one, complete and functional utility system meeting the object requirements. There is an assumption that the automation system MASTER on its every organisational level can cooperate with other IT systems, ensuring at the same time transparent configuration solutions. Presented are here, aginst the background of the DCS MASTER organisational structure, its various integration mechanisms used during the realisation of complex automation DCS MASTER systems including heterogeneous turnkey installations.

Cooperation of the DCS MASTER system with database and data storage systems
Presented are problems connected with data processing and handling data storage systems in the system DCS MASTER as well as with exchanging data with data storages of external systems. There is an assumption that the automation system MASTER on its every organisational level can cooperate with other IT systems, ensuring at the same time transparent configuration solutions. In older solutions the mentioned superior systems were provided by IASE with the use of Windows Servers 2008. Currently, proposed are also NAS network servers produced by Synology, QNAP or Dell with the dedicated for them operating softwares. Depending on requirements from the side of users and the size of the DCS MASTER automation system installation it is possible to offer solutions basing either on the most standard file servers or on the ones that will take account of additional functionalities provided by the modern NAS platforms.

Perspectives of plasma technology application in the domestic power sector
Presented is an overview of plasma technologies used in power industry for production of energy from coals. Characterised are the most often applied thermal plasma sources used in dust burners and reactors used in combustion/gasification/pyrolysis processes. Described is the experience gained from application of plasma technology in boiler plants and gasifying reactors. Discussed are proposals concerning the use of thermal plasma in a technology cycle of fuel processing in pulverised fuel power boilers with the special attention paid to their work in conditions of the reduced technical minimum.

Diagnostics base to approach safe operation and high availability of power units 200 MW class
The classic diagnostics accompanying the basic operation of power units has been loosing its usefulness for a long time. The effects of this are not yet clearly visible as cycle load is still relatively mild and failure analysis very rarely points that the reason for operation damages is cycle load. For a long time Pro Novum promotes, implements and develops diagnostics adapted to flexible operation of power units, especially those 200 MW class. Its methodology has a form of „Guidelines…” and software supporting the diagnostics performed in the scale of power unit, power plant, group of power plants and National Power System.

Portal Bloki PRO® – innovative tool to create and manage knowledge on technical condition of power units class 200 MW
Significant similarity of construction, operating conditions (still) and technical condition of power units 200 MW class made as develop the tool, which suits best among known on the market diagnostic systems to assure low-cost safety and high availability of this class of power units, the most important class in National Power System now and in foreseeable future. Portal Bloki PRO® integrates all users of power units 200 MW class. Portal is a logical continuation of our project LM System PRO+® ver. 4.0, is constantly being developed and its ver. 2.0 is currently being created. The paper will present among others the benefits to be achieved when using its current and future capabilities.

Approach to maintenance in ENERGA Elektrownie Ostrołęka SA as a method of success on the Power Market
Is there a place for the longtime-operated 200 MW power units on the Power Market? The provisions in the legal Act create new requirements (not yet fully known) for 200 MW class power units. It means that generating units must be in the perfect technical condition and so-called half-measures in the area of maintenance cannot exist. Therefore, knowledge about technical condition of components should (must!) be a priority. Moreover, with no current update of such knowledge, ensuring high availability will be impossible and for this reason profitable participation in Power Market will be in doubt.Adaptation (not only) to the Power Market required a change in the approach to asset management. Due to permanent changes, the strategy had to be directed to the safe operation of generating components and their good technical condition based on the reliable and constantly updated knowledge.

Impact of fatique and creep phenomena on technical condition of main steam pipelines of power units class 200 MW operated over limit temperature for a long time
The main steam pipelines, not only of power units 200 MW class, were not designed for fatigue. So far, cycle load is not a source of fatigue damages. Our long-time tests of high-pressure steam pipelines show that fatigue and creep damages, even on the installation operated over 300 000 hours, occur only in the presence of additional stresses related to repair and/or operating irregularities. It is more often to encounter negative effects of pipeline vibrations caused by hydraulic impacts and/or insufficient dehydration of horizontal sections.

Vibration measurements of heating pipelines
The paper discusses the results of vibration measurements of pipelines in chambers of heating network of Warsaw capital city ordered by Veolia Energia Warszawa S.A. The measurements have been made in different working parameters of installation in a heating period. The purpose of testing was to check if it is possible to determine the location of leaks (failure) on the basis of vibrations.
