Embodiment 1
[0058] This embodiment provides a clock bias correction method, which is used for correcting the clock bias among various online power quality monitoring devices in the power grid.
[0059] refer to figure 1 , the clock bias correction method provided in this embodiment includes the following steps:
[0060] Step S100: Obtain the frequencies monitored by each monitoring device at each moment.
[0061] Specifically, in practical applications, corresponding monitoring equipment is installed in each substation, and the power quality in the substation area is monitored through the monitoring equipment. Each monitoring device uploads the monitored data to the main station of the power grid according to a preset period, for example, uploading the monitoring data every three minutes or five minutes. In this embodiment, the system frequency of each substation is monitored by the monitoring equipment. Since the frequency of each place in the power grid is consistent at the same time,...
Embodiment 2
[0122] This embodiment provides a clock deviation correcting device, which is used for correcting clock deviations among various online power quality monitoring devices in a power grid. refer to Image 6 The device for correcting clock bias provided in this embodiment includes a first acquiring unit 20 , a first determining unit 21 , a second determining unit 22 and a correcting unit 23 .
[0123] The first acquiring unit 20 is used to acquire the frequencies monitored by each monitoring device at each moment;
[0124] The first determination unit 21 is used to determine the abnormal frequency equipment and the normal frequency equipment corresponding to each time according to the frequency monitored by each monitoring equipment at each time;
[0125] The second determination unit 22 is configured to determine the first target frequency corresponding to each time according to the frequency monitored by the normal frequency equipment corresponding to each time;
[0126] The c...
Embodiment 3
[0130] The embodiment of the present application also provides a computer device, such as Figure 7 As shown, the computer device includes a memory 100 and a processor 200 . Wherein, the memory 100 and the processor 200 are communicatively connected to each other, and may be connected through a bus or in other ways, Figure 7 Take connection via bus as an example.
[0131] The processor 200 may be a central processing unit (Central Processing Unit, CPU). The processor 200 may also be other general-purpose processors, digital signal processors (Digital Signal Processor, DSP), application-specific integrated circuits (Application Specific Integrated Circuit, ASIC), field-programmable gate array (Field-Programmable Gate Array, FPGA) or Other chips such as programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, or combinations of the above-mentioned types of chips.
[0132]As a non-transitory computer-readable storage medium, the mem...
