Diagnostics, repairs and service of turbine components nuclear and latest generation conventional power units
For almost 40 years, Pro Novum has specialised in the diagnostics, repairs, and servicing of long-operation steam turbines, which continue to be the base for the safe transformation of the Polish energy sector. The expertise acquired in this area is applied to the diagnostics of the latest generation of steam turbines and generators, wind turbines, and turbines in nuclear power plants. Selected examples of diagnostics supporting the repair of generator rotors at the Chmielnicka Power Plant (Ukraine), diagnostics and repairs of rotors of recently operated steam turbines of the latest generation, and diagnostic services supervising the safe operation of repaired components, performed remotely using modern design modeling and safety assessment technologies, are presented.

Decades of expertise: Kurita’s unique technologies for nuclear cooling water management (ensuring safety, compliance, and operational continuity)
Water treatment is essential for maintaining the performance, safety, and longevity of nuclear power stations. The large volumes of water used in cooling systems are prone to issues such as scaling, corrosion, biofouling, and sediment accumulation, which can impair heat transfer efficiency and damage critical infrastructure. To prevent these problems, comprehensive treatment programs – including raw water pretreatment, chemical dosing, biocide application, and monitoring – are implemented to control water quality and system integrity. Proper cooling water treatment ensures optimal thermal performance, reduces operational risks, complies with environmental regulations, and supports the safe, continuous operation of nuclear facilities. Kurita has decades of experience in water treatment in nuclear power industry and has introduced several unique technologies in this field.

Upgrading and servicing of large nuclear steam turbines
The nuclear energy industry is experiencing renewed growth due to rising electricity demand and a focus on low-carbon energy sources. In many countries, the growth is promoted by government support and accelerated by technological advancements. Presently, more than 70 gigawatts of new nuclear capacity is under construction globally and more than 40 countries around the world have plans to expand the role of nuclear power in their energy systems. In addition to new builds, an increase in nuclear capacity is also possible through uprating of existing nuclear power plants. Reactor thermal power uprates are usually associated with steam turbine upgrades which result in power output increase, lifetime extension, reliability improvement and reduction in maintenance costs. GE Vernova offers a wide range of upgrade solutions and services for large (around 1000 MW or more power output) nuclear steam turbines. These include retrofits of high-pressure and low-pressure turbine modules, component upgrades, uprate feasibility studies and outage deferment studies. These offerings are based on extensive experience with nuclear steam turbines, recent developments in steam turbine technology and employ state-of-the-art engineering tools and methods in project execution.

Diagnostic service in the LTDSA formula is a source of benefits for the investor and user of new power units and energy devices
At least the most technologically advanced components of new power units and equipment, including combined cycle and gas units, are covered by the supplier’s long-term service agreement (LTSA). This ensures the safety and availability of the equipment for the investor / user, while simultaneously limiting their knowledge of its current technical condition. LTSA service creates an additional, significant source of revenue for the supplier by influencing the maintenance strategy. Concurrent LTDSA (Long-Time Diagnostic Service Agreement) service balances the supplier’s and user’s competencies in maintaining the technical condition, which is particularly important when troubleshooting problems related to identifying the causes of irregularities, especially those of an emergency nature.

Windows – a new operational platform of the DCS MASTER system
Presented are the latest news which enriched the Polish automation system DCS MASTER. One of them is the possibility to implement the SO system on the Windows operational platform that enables, among the others, realization of the DCS MASTER „2w1” system small installations. At the same time, the SKP-MGate and SO operator systems are installed on a small-size equipment or PC computers that is an optimum solution for small object installations. With the aim to safeguard the system against potential cyberattacks its networks have been expanded by new categories to make the installation back-up copies as well as to monitor and eliminate a suspicious network traffic. As always, the strong advantages of the Polish automation system are its transparent structure, modular design and free-form scalability tailored to a user’s needs, simplicity of integration with other producers’ systems as well as realization of unconventional user’s requirements that all in all reflects in competitiveness against other companies’ systems. DCS MASTER system has been implemented in Poland on many power facilities and in various variants from single „2w1” stations to complex turnkey object installations.

Scheduling of an energy storage integrated with a hybrid supply system connected to the mains with the use of genetic algorithms
The article deals with the effective energy management in hybrid supply systems composed of RES and an energy storage. Elaborated and compared is the effectiveness of two strategies to control an energy storage operation: classical rule-based method and the author’s optimization method using the genetic algorithm. The function of the genetic algorithm aim was defined as the maximization of the economy profit from energy trading considering dynamic energy prices. Simulation studies were realised in the MATLAB/Simulink environment for an annual time horizon on the basis of the real meteorological and market data. Obtained results showed that using the genetic algorithm enabled generation of a bigger operational profit and the payback time reduction for more than 8 years (from 20, 32 years for the rule-based method and to 12, 24 years for the author’s optimization one) despite the more intensive utilisation of the storage. In conditions of the volatile energy prices the advanced optimization methods using price arbitration are much more economically justifiable than the simple rule-based control aimed exclusively at covering of the own needs.

Optimization of external LFC nodes systems installation with the use of the company’s communication and processing station SKP-MGate
Multiannual experience of the Instytut Automatyki Systemów Energetycznych Sp. z.o.o in various fields of manufacture and operation of ARCM/LFC systems has resulted in elaboration in the recent years of a system to handle External LFC Nodes of a trade name „System Rozdziału Mocy LFC” (SRM LFC) that meets all requirements described in LFC system normative documents issued by PSE S.A. On the basis of the SRM LFC system there are built WL LFC Local Nodes and the WW LFC External ones under a common name External Nodes WZ LFC implemented at the members of the Energy and Power Balancing Market. The system is intended to control power plant blocks of the Centrally Dispatched Generating Units (JWCD) and units not being centrally dispatched by PSE (nJWCD). In the feedback the external nodes provide actual values of every individual JWCD and nJWCD block working parameters to the node of the central System of Working Parameters Monitoring (WC SMPP). The WL LFC system has already been successfully implemented in several Polish power plants – conventional and hydropower ones.
