Embodiment 1
[0050] Such as figure 1 As shown, a method for checking abnormal fluctuations in power consumption of electricity customers includes the following steps:
[0051] S1: Acquire and standardize the full amount of user data from the grid marketing system;
[0052] In a specific embodiment, first obtain the full amount of user data from the grid marketing system, divide the data of each user with the user billing cycle month as the minimum time period, and eliminate the users who have business that affects power fluctuations in the current month, More specifically, the services that affect power fluctuations include: users increase usage capacity this month, and users handle equipment deactivation.
[0053] S2: Classify the normalized user data according to the user's power consumption characteristics, extract the user's historical power consumption, and mark whether there is an error according to the historical settlement of power consumption and actual power consumption;
[005...

The invention discloses a method for checking abnormal fluctuations in power consumption of electricity customers, comprising: S1: obtaining a full amount of user data and performing normalized processing; Whether the electricity status mark is wrong; S3: Calculate the user’s power comparison change value and set the threshold corresponding to the power comparison change value, and based on this, obtain a new error classification for screening normal users and abnormal users; S4: Construct a classification curve to judge the current Availability of the classification method, if the classification method is available, the corresponding value of the inflection point of the curve is the optimal value of the threshold, and the screening conditions are obtained accordingly; S5: Screen and check the new settlement electricity bill; S6: After the system has been running for a period of time, select The recent historical users are used as analysis samples, and S4 is repeated to obtain a new inflection point value and adjusted accordingly. The present invention reduces the manual checking workload and improves checking efficiency while controlling the number of checking omissions, that is, controlling the amount of errors.
Description
technical field [0001] The present invention relates to the technical field of electric power systems, and more specifically, to a method for checking abnormal fluctuations in power consumption of electricity customers. Background technique [0002] Under the background of power system reform, with the opening of the electricity market, electricity customers have gradually changed from the current seller's market to the buyer's market, so electricity customers are paying more and more attention to the quality of power supply services. The power supply unit analyzed the complaints about the service quality of electricity customers, and found that a considerable part of the complaints was that the electricity customers reported that they were slow to receive electricity bills. The reason for the slow issuance of customer electricity bills is that a considerable part of the calculation results of the customer's settlement electricity bills are detected by the electricity bill a...
