Abstract: Method for time synchronization of sensor units (SU) in a distributed system, wherein sensor data (SD) is captured by the sensor units (SU) and transmitted to a central unit (CU) via a radio network, and that, upon capture of sensor data (SD), a further current value of the internal time unit (FC) of the respective sensor unit (SU) is stored, that the captured sensor data (SD) is assigned at least the value of the internal time unit stored upon receipt of the characteristic time feature of the identification signal, the associated transmitter identification of the identification signal, and the further value of the internal time unit (FC) stored upon the capturing of the sensor data (SD) and transmitted together with the sensor data (SD) to the central unit (CU), and wherein the central unit (CU) captures voltage and phase values from at least one of the three phase conductors of a power supply network from which synchronization data (t0EGSp, Tp) for the frequency or period and the phase angle of the voltage of at least one of the three phase conductors in relation to the time of capture of the voltage and phase values of the at least one of the three phase conductors is ascertained and transmitted to the sensor units (SU), and the respective sensor unit (SU) captures the respective sensor data (SD) in the form of current values in relation to synchronization data (t0EGSp, Tp), which is transmitted to the central unit (CU) and, in the central unit (CU), powers are calculated from the voltage values and current values.
