The invention relates to a method and system for detecting power supply and outage information. The method comprises the following steps: reading the power supply and outage state of a client of a distribution transformer district from electric terminal equipment corresponding to a distribution transformer every set duration, including a power supply state and an outage state; recording a first reading moment for currently reading the power supply and outage state and a second reading moment for reading the power supply and outage state last time if the currently read power supply and outage state is different from the last read power supply and outage state; determining an intermediate value of the first reading moment and the second reading moment as a power outage moment if the power supply and outage sate is a power outage state; and determining the intermediate value of the first reading moment and the second reading moment as a power supply recovery moment if the currently power supply and outage state is a power supply state. The method and system can be used for efficiently and accurately detecting the power supply information of clients in the distribution transformer district.
Description
technical field [0001] The present invention relates to the technical field of electric power, in particular to a method and system for detecting power supply and power failure information. Background technique [0002] At present, customer power consumption information management based on power supply reliability is only popularized to medium-voltage users, and user power consumption data collection mainly relies on power terminal equipment such as power collection terminals installed on 10kV distribution transformers. (Distribution transformer) manages electricity consumption information for a household. The above-mentioned electricity consumption information management method, for special transformer customers, can basically detect the power supply information such as the time of power outage, the time of power supply and the duration of power outage. However, for a distribution transformer with a wide power supply range, such as a public distribution transformer with a p...
