This paper presents the STATCOM model in PSIM, which compensate reactive power and current harmonics from the non-linear load. Reactive power consumption and harmonics current of non-linear load given from measurement. The model of STATCOM is a multi-level voltage inverter. Constant system voltage, power factor and harmonics currents are controlled. All modes are realized and plots are plotted.

Reliable and economical operation of the equipment of thermal heat supply systems and boiler installations is an important and challenging task. High-quality water treatment directly affects the efficiency of boiler installations. The main stages of water treatment at thermal power plants are pretreatment, desalination and thermal deaeration — removal of aggressive gases that lead to corrosion of equipment. Currently, there are a significant number of manufacturing enterprises that are equipped with their own boiler plants. In boiler houses used for steam generation, as well as heating boilers serving heating system, water deaeration is a mandatory process. The article is dedicated to the development of a technology to make the boiler installations more economical and efficient due to additional heating of the return system water with deaerator flash steam. In this paper, the process of water deaeration is considered on the example of the boiler room of the AB InBev Efes brewery in Ulyanovsk, where the heating station is equipped with automation systems, and the regulation of steam supply for heating is carried out automatically depending on the temperature of the return system water. Due to the designed arrangement and depending on the amount of flash steam of the atmospheric deaerator, the return water of the heating system can be heated by 3 - 10°C. Besides, during periods of warm winters at the Ulyanovsk-based brewery of AB InBev Efes, with minimal loads of the boiler plant, heating of the return system water in the heat exchanger with the flash steam of the atmospheric deaerator may be used as the main or additional stage of heating.

Poor healing wounds are a rather difficult problem for doctors, since they complicate even the most successful treatment. For example, in diabetes mellitus wounds arise due to injured vascular disease, with oncology and HIV-due to suppressed immunity, and in the elderly the reason is the low rate of cell division. The treatment of such wounds by the usual methods is very problematic, and sometimes it is simply impossible. It is also complicated because of the fact that such wounds usually have large sizes and complicated forms. It is possible to solve these problems with the help of low-temperature plasma. The article considers the possibilities of using a cold plasma stream, its sterilizing and disinfecting properties. There are a lot of methods of sterilization and disinfection available in the world. The use of solutions of chemical agents, boiling, ionizing radiation, dryers, gas sterilizers have their advantages and disadvantages. Cold plasma can be used not only for therapeutic influences, but also for the treatment of tools and materials for the treatment of intradermal infection. The structure of the construction, which allows to increase the area of treatment with cold plasma jets, is proposed. The possibility of processing difficult-to-reach areas and objects of complex form is considered. In the conclusion, an analysis was made of the use of the design of a multi-stream creep plasma generator for therapeutic effects and to achieve antibacterial effects. Keywords: cold plasma; multi-jet cold plasma generator; pin-to-hole discharge. 1. Introduction. The modern period of development of medicine is characterized by an increase in the number of surgical infections and postoperative purulent-inflammatory complications. It is based on general biological reasons, which are based on changes in the immunological resistance of the human body, as well as the causes associated with technical progress. The possibility of invasion of chronic infectious agents is increasing due to the increase in traumatism, the volume and duration of surgical interventions, as well as the wide use of various technical means of synthetic implants, metal constructions, intravascular catheters, etc. Sterilization and treatment of open wounds, burns of complex form, as well as surgical instruments and various constructions can be performed using a stream of cold plasma jets. Cold plasma has a wide range of applications due to its ability to control its physical and chemical parameters. Numerous experiments in vivo and in vitro show that low-temperature atmospheric plasma has a valuable health impact with high potential applications: antibacterial, fungicidal and antiviral; disinfection of tissues [1-3], treatment of wounds and burns [4-6], therapy in oncology and dermatology [7-9], sterilization of different surfaces and food [10-13], etc. Various plasma parameters such as a mix of ions / electrons, their spatial and energy distributions, temperature, power, light radiation spectrum, jet shape and environmental conditions affect the conv...
