Description
Przez T0 oznaczo¬ no okres stalej czestotliwosci a przez T — okres powtarzania impulsów synchronizacyjnych, przy czym T = nTG, gdzie n — liczba calkowita. Przez t. oznaczono czas przejscia impulsu synchroniza¬ cyjnego z punktu centralnego do punktu pomiaro- 74 99874 996 wego i. Przykladowo sposób wedlug wynalazku moze byc zastosowany do pomiaru napiecia, pradu lub mocy jednoczesnie w kilku punktach systemu energetycznego.Zainstalowane w punktach pomiarowych genera¬ tory o stalej czestotliwosci laczy sie odpowiednimi laczami z generatorem takiej samej czestotliwosci zainstalowanym w punkcie centralnym, który przy pomocy impulsów synchronizacyjnych utrzymuje równomierna prace wszystkich generatorów. Wy¬ dany w punkcie centralnym sygnal rozpoczecia po¬ miarów wysylany jest do punktów pomiarowych jednoczesnie z najblizszym impulsem synchroni¬ zacyjnym i dociera do punktów pomiarowych po pewnym czasie tv zaleznym od oddalenia danego punktu od punktu centralnego.Nastepny impuls synchronizacyjny, generowany jednoczesnie przez wszystkie generatory jest sy¬ gnalem rozpoczynajacym pomiar. PL PLT0 denotes the period of the constant frequency and T denotes the repetition period of the synchronization pulses, where T = nTG, where n - integer. The t. Denotes the time of passage of the synchronization pulse from the central point to the measurement point i. For example, the method according to the invention can be used to measure voltage, current or power simultaneously at several points of the power system. The tracks with a constant frequency are connected by appropriate connectors to the generator of the same frequency installed in the central point, which, by means of synchronization pulses, maintains the uniform operation of all generators. The signal to start the measurements at the central point is sent to the measurement points simultaneously with the next synchronization pulse and reaches the measurement points after a certain time tv depending on the distance of the given point from the central point. The next synchronization pulse, generated simultaneously by all generators is the signal that starts the measurement. PL PL
