Abstract: FIELD: electrical engineering.SUBSTANCE: invention relates to electrical engineering, to devices for relaying protection of alternating current machines from inter-winding faults (IWF) in the stator winding. According to the proposed method, the formation of a control action on the shutdown of the machine is carried out with a decrease in the IWF coefficient relative to the operation setpoint. The actual value of the IWF coefficient function is corrected by calculating the damaged generator model and calculating the IWF coefficient in emergency mode. Compliance with the balance of the equations of equilibrium of e.m.f and the voltage drop at the terminals of the machine is monitored, and if the error threshold is exceeded, a signal is generated that blocks the protection operation. There is parallel simulation of the operation of the machine with the calculation of the compared values, which are taken as reference values in the process of operation. The adaptive properties of the algorithm are manifested in automatic adjustment during the actual determination of the IWF coefficient, using both physically measured parameters of the machine and indirect ones obtained through simulation, as a result, it is possible to identify damage up to one winding. The principle of combined protection is detuned from external unbalanced modes and in combination with the well-known method for transverse differential protection of the generator has high sensitivity and reliability of operation, and makes it possible to determine the place of damage and the quantitative value of the damage.EFFECT: increasing sensitivity of protection against inter-winding faults in the stator winding and expanding the field of application due to the possibility of using it in AC machines with an unsplit stator winding.1 cl, 1 dwg

Abstract: FIELD: data networks. 
     SUBSTANCE: invention relates to the field of services provided in data networks based on unidirectional selective call sessions, including direct talk (PTT), under the control of a PT server within the framework of a service based on SIP (Session Initiation Protocol). To achieve the effect, when establishing a group packet voice communication session over data transmission networks, the first user terminal sends a request to establish a group packet voice communication session to the multicast server via a signaling channel to initiate a connection between the server and the user terminal; the multicast server receives a request to establish a multicast session of packet voice communication from the first user terminal and creating a network route between the multicast server and user terminals, including at least transmitting a server connection request to the user terminals of the group, and transmission by the user terminal of voice packets to the multicast server, the created network route between the multicast server and the user terminals is maintained in an active state by sending repeated registration packets or keep-alive packets, the transmission of voice packets to the multicast server is also performed via signaling channels using the user datagram. Each voice packet is a request to establish a group packet voice session and contains information necessary to initiate a connection between the server and the user terminal. 
     EFFECT: reduction of the time to establish a multicast service due to the fact that a communication session begins without a preliminary exchange of signaling messages, and immediately upon receipt of the first voice packet.
