Patent RU-2746796-C1 (RU)
Inventor: Klimash Stepan Vladimirovich
IPC: H02M3/18

Abstract: FIELD: electrical engineering.  
     SUBSTANCE: invention relates to electrical engineering and is intended for static compensators of reactive power in power supply systems. A method is proposed for controlling reactive power by a capacitor unit with three banks of capacitors, each of which is connected to the network by two thyristor switches and a mains switch. When each bank of capacitors is turned on, two phases are first turned on at the moment the line voltage of these two phases passes through zero, and then the third phase is turned on at the moment the phase voltage of this phase passes through zero. When each capacitor bank is disconnected, one phase is first disconnected naturally, in which the current passes through zero earlier, and then two phases are disconnected, the total current in which crosses zero. A distinctive feature of the method is that the capacity of the second capacitor bank is twice that of the first, and the capacity of the third capacitor bank is twice that of the second. The first stage of reactive power regulation is switched on by connecting the first capacitor bank to the network, the second stage of reactive power regulation is switched on by switching on the second capacitor bank when the first capacitor bank is disconnected, the third stage is switched on by connecting the first capacitor bank in parallel to the second capacitor bank, switching on the fourth control stage reactive power is produced by turning on the third capacitor bank when the first and second capacitor banks are disconnected, the fifth stage is turned on by connecting the first capacitor bank in parallel to the third capacitor bank, the sixth stage is turned on by connecting the second capacitor bank in parallel to the third capacitor bank when the first capacitor bank is disconnected, and the seventh stage of reactive power regulation is switched on by connecting the first battery capacitor banks in parallel to the second and third capacitor banks. 
     EFFECT: reducing the number of switching devices while maintaining the accuracy of the multi-stage reactive power control by the capacitor unit and in increasing the reliability of power supply systems.

     SUBSTANCE: invention relates to the field of operation of oil and gas wells and can be used to improve the quality of their construction. A method for wave treatment of oil and gas wells is proposed, including drilling a well using a bit with flushing holes, preparing drilling mud and feeding it into the bit while drilling a well, securing the drilled hole by lowering metal casing strings, followed by preparing a grouting solution and plugging the area between the casing and the borehole wall, and before drilling the well, wave generators are installed in the drilling holes of the bit to create a clogging screen during drilling, a drilling fluid is prepared by dispersing and homogenizing the mixture in a wave generator to prepare a drilling mud with clogging properties, while drilling slurry in the bit with the possibility of passing it through wave generators in the flushing holes of the bit, the grouting slurry is prepared by dispersing and homogenizing the mixture in a wave generator and it is pushed into the cavity between the casing and the borehole wall. For the implementation of the method, various wave generators are used, equipped with a static system of wave stimulators.  
     EFFECT: use of the proposed wave generators in the proposed method gives a systemic effect, expressed in a significant improvement in the quality of oil and gas wells.

Abstract: FIELD: water supply. 
     SUBSTANCE: invention relates to the field of water supply, in particular to methods of controlling pumping units and is intended to improve the energy efficiency of their operation and to provide protection for the cavitation reserve (NPSH). According to the method, the approximated functions of the pressure-flow characteristic, the hydraulic efficiency and the cavitation margin (NPSH) are constructed for different operating frequencies of the pumping unit according to the data from the pump unit's passport. Based on the specified functions and the results of measurements of the current values of the pressure, power and frequency of operation of pumping units, the energy efficiency of the current operating mode of the system is determined. Further, using these functions, the frequency of operation and possible energy efficiency are determined in the new operating mode, in which one or more additional pumping units are switched on or off in the system. Then the specified new mode of operation is switched, provided that more energy efficient and protection according to NPSH are provided.  
     EFFECT: increase in the energy efficiency of the pumping units without the need for additional measuring equipment, a simplification of the method, and an increase in the safety of work.
