Granted: 2002-12-27
Abstract: FIELD: radio engineering, radio communication. SUBSTANCE: method and device are intended for determination of frequency shifts caused by error of generator or by Doppler effects in subscriber's terminal in communication system. System includes one subscriber's terminal as minimum and base station or interface station to establish communication through satellite. Communication signal 500 is corrected in advance with due account of known Doppler effects by interface stations and transmitting satellite, for example, if satellite is employed, and is transmitted to subscriber's terminal. Subscriber's terminal determines signal frequency with reference to reference frequency generator 516, 518 and treats any detected difference as difference completely emerging as result of Doppler shift. Frequency difference is transmitted either in the capacity of data in transmission over feedback lines 524, 526 or is used as coefficient 522, 526 of preliminary correction for such transmissions. Signal frequency of subscriber's terminal in feedback line is measured at interface station 528 with new compensation for known Doppler effects to ensure measurement of nominal error 530. Measured frequency error and frequency shift are then divided in two to obtain error of Doppler shift or divided in two and scaled to proper frequency to obtain error of generator 532 of subscriber's terminal. Detected error can be sent to subscriber's terminal 534 for utilization in correction of output frequency of generator or for adjustment of its synchronization or for time tracking for subscriber's terminal. On the other hand, detected error can be included as data in following signals for use by interface stations or by base stations 538, 540. EFFECT: enhanced speed of response. 32 cl, 6 dwg

Title: Model of the steam-water section of a generating unit
Inventor: Tsyrulnyk Fedir Petrovych
Filed: 1999-03-24
Abstract: The proposed model of the steam-water section of a generating unit provides the possibility to simulate transit-time effects of the steam-water section depending on the generating unit load. For this purpose, the model contains a squarer, which is connected to the input of the integrator of the signal proportional to the thermal load, and a unit for determining the difference of the squared pressure values, which is connected to the said integrator output. The integrator provides for simulating the capacity of the steam-water section, and the unit for determining the difference of the pressure squared values is designed for simulating the hydraulic resistance of the steam-water section. The transit-time effects of the steam-water section depend also on positions of the turbine control valves. For simulating the positions of the turbine control valves, the proposed model contains a divider. The proposed model provides for increasing simulation accuracy in the sliding pressure mode, at the constant positions of the turbine control valves, and as a result, decreasing a number of deviations of the actual operation parameters from the normal operation mode parameters when starting, adjusting, and testing the control systems of the generating unit.
