As shown in fig. 2, the method includes:
S201, obtaining current information to be detected, which is transmitted by the power information acquisition equipment, wherein the current information to be detected comprises a station area residual current value of a low-voltage station area and user side reference current values corresponding to the user side electric meters.
S202, determining a corresponding user side residual current value according to the difference between the live wire current value and the zero wire current value in the user side reference current values for each user side ammeter.
In this embodiment, for each user-side ammeter, the difference between the live current value and the neutral current value in the user-side reference current value is taken to obtain a vector difference, and the vector difference is determined as the user-side residual current value of the corresponding user side, as shown in the following formula ：IRi＝ILi-INi,IRj＝ILj-INj,……IRn＝ILn-INn.
Wherein, I Li、ILj … … is the live wire current value of the ith user and the j … … th user respectively; i and j epsilon [1, n ], n users in the platform region, I Ni、INj … … are zero line current values of the I and j … … users respectively, and I Ri、IRj … … is a residual current value of the I and j … … users at the user side respectively.
S203, determining a total value of the residual current of the user side according to the sum of the residual current values of the user side corresponding to the electric meters of the user side.
In this embodiment, the user-side residual current values of the electric meters on the user sides are obtained based on the above steps, the sum of the residual current values on the user sides is taken to obtain a vector sum, and the vector sum is determined as the total value of the residual currents on the user sides of all the users in the low-voltage transformer area. The following formula is detailed: i RU＝IRi+IRj+……IRn.
Wherein I Ri、IRj … … is the user side residual current value of the I and j … … th users, and I RU is the sum of the user side residual current values, namely the total value of the user side residual currents.
S204, if the residual current value of the transformer area meets the transformer area leakage condition, determining leakage fault information according to the residual current value of the transformer area, the residual current value of each user side and the total residual current value of the user side, and determining the leakage fault information as a leakage fault detection result.
In this embodiment, the platform leakage condition is that the platform residual current value is greater than a preset threshold value, for example 300mA. The leakage fault information can be understood as related information of the leakage fault existing in the low-voltage transformer area, including the leakage position and corresponding leakage ammeter information.
Specifically, if the residual current value of the transformer area does not meet the transformer area leakage condition, that is, if the residual current value I RD <300mA of the transformer area, it is indicated that no leakage fault occurs in the transformer area, the current leakage fault-free state is determined as a leakage fault detection result, and no further operation is needed. When the residual current value of the platform area meets the platform area leakage condition, namely I RD is more than 300mA, comparing the residual current value I RD of the platform area with the total residual current value I RU of the user side, determining that the leakage position is one or more of platform area leakage, user leakage measurement and transmission line leakage according to the comparison result, determining leakage ammeter information of the leakage user side based on the residual current value of each user side when the leakage of the user side exists, and determining the leakage position and/or the leakage ammeter information as leakage fault detection results.
Optionally, determining the leakage fault information according to the platform area residual current value, each user side residual current value and the total user side residual current value includes:
S2041, comparing the total value of the residual current at the user side with the residual current value of the station area to obtain a comparison result.
In this embodiment, the comparison result may be understood as a comparison result of the total value of the residual current at the user side and the residual current value of the platform area, which is a difference value between the total value of the residual current at the user side and the residual current value of the platform area.
Specifically, a difference value between the total value of the residual current at the user side and the residual current value of the platform area is taken, and the difference value is determined as a comparison result.
And S2042, when the comparison result meets the first condition, determining that the current leakage fault is user side leakage, determining corresponding leakage ammeter information according to residual current values of all user sides, and determining that the current leakage fault is user side leakage and the leakage ammeter information is leakage fault information.
The first condition is that the difference between the residual current value of the platform area and the total residual current value of the user side is smaller than a preset leakage difference value, for example 100mA. The leakage ammeter information is the ammeter number corresponding to the ammeter at the user side, the corresponding user number, the residual current value at the user side and the like.
Specifically, because the residual current value of the platform area meets the platform area leakage condition, the residual current value of the platform area is larger than 300mA, when the total value of the residual current of the users in the platform area is approximately equal to the residual current of the platform area and is larger than 300mA, and the difference value is smaller than the preset leakage difference value, namely I RU≈IRD >300mA, and when the IRD-IRU is smaller than 100mA, the platform area is only subjected to post-meter leakage, namely the users in the platform area are only subjected to leakage faults, and the power transmission line of the platform area is not subjected to leakage faults. At this time, the electric leakage user side ammeter is determined according to the magnitude of the residual current value of each user side, and corresponding electric leakage ammeter information is determined.
And S2043, when the comparison result meets the second condition, determining that the current leakage fault is the electric transmission line leakage, determining whether the current leakage fault meets the user side leakage condition according to the residual current value of each user side, if so, determining corresponding leakage ammeter information according to the residual current value of each user side, determining that the current leakage fault is the electric transmission line leakage and the user side leakage, and determining that the leakage ammeter information is the leakage fault information, and if not, determining that the current leakage fault is the electric transmission line leakage.
The second condition is that the area residual current value is greater than the total value of the residual current at the user side, and the difference between the area residual current value and the total value of the residual current at the user side is greater than a preset leakage difference, for example 100mA. The user side leakage condition may be understood as a condition for judging whether there is a post-user side leakage, for example, that the user side residual current value is greater than a preset user residual current, for example, 30mA.
Specifically, since the platform area residual current value meets the platform area leakage condition, the platform area residual current value is greater than 300mA, and when the platform area residual current value is greater than the user side residual current total value and the difference between the platform area residual current value and the user side residual current total value is greater than the preset leakage difference value, i.e. I RD >300mA and I RD-100mA>IRU, it is indicated that the platform area has pre-meter leakage, i.e. a leakage fault exists in the platform area power transmission line. At this time, it is explained that there is a post-meter leakage (user side leakage) in the station area in addition to the pre-meter leakage (transmission line leakage), the leakage ammeter information of the leakage user side ammeter is determined, and the current leakage fault is determined as transmission line leakage and leakage ammeter information as leakage fault information. Judging whether the current residual current value of the user side is larger than the preset residual current of the user side, if so, determining the ammeter information of the corresponding ammeter of the user side, and determining the current leakage fault as the leakage of the power transmission line and the leakage of the user side and the leakage ammeter information corresponding to the leakage of the user side as leakage fault information; if not, the current leakage fault is determined as leakage fault information of the power transmission line.
Further, determining corresponding leakage ammeter information according to the residual current value of each user side includes:
a1 For each user side residual current value, when the user side residual current value is larger than the preset user residual current, determining a user side ammeter corresponding to the user side residual current value, and determining leakage ammeter information of the user side ammeter.
In this embodiment, the preset user residual current is a preset maximum threshold value of the user side residual current.
Specifically, for each user side residual current value, judging whether the corresponding user side residual current value is larger than a preset user residual current value, if not, determining that the corresponding user side is a normal user, and no leakage fault exists; if yes, determining that the corresponding user has the leakage fault, determining the user side ammeter of the user, and further determining the leakage ammeter information of the user side ammeter.
The embodiment of the invention provides a leakage fault detection method, which comprises the steps of obtaining current information to be detected, which is transmitted by electric power information acquisition equipment, wherein the current information to be detected comprises a station area residual current value of a low-voltage station area and user side reference current values corresponding to electric meters at each user side; for each user side ammeter, determining a corresponding user side residual current value according to the difference between the live line current value and the zero line current value in the user side reference current value; determining a total value of the residual current of the user side according to the sum of the residual current values of the user side corresponding to the electric meters of the user side; if the residual current value of the transformer area meets the transformer area leakage condition, determining leakage fault information according to the residual current value of the transformer area, the residual current value of each user side and the total residual current value of the user side, and determining the leakage fault information as a leakage fault detection result. According to the technical scheme, through a series of discriminant rules and logics, quick investigation detection and positioning of the electric leakage fault are realized, compared with manual electric leakage investigation monitoring, electric leakage fault detection and positioning are automatically realized, labor cost of electric leakage fault detection is reduced, staff is assisted to quickly narrow an investigation range, investigation workload of the staff is reduced, and electric leakage fault detection efficiency is improved.
Fig. 3 is a flowchart of another leakage fault detection method according to the second embodiment of the present invention, where, as shown in fig. 3, a station area residual current value of a low-voltage station area, a live line current value and a neutral line current value corresponding to each user-side electric meter, which are transmitted by an electric power information acquisition device, are obtained; and determining a user side residual current value of the corresponding user according to the live wire current value and the neutral wire current value of each user, and determining a user side residual current total value of the station area according to the sum of the user side residual current values corresponding to each user.
Judging whether the residual current value of the station area is larger than a first threshold value of 300mA, if not, determining that no leakage fault exists in the station area; if yes, determining that an electric leakage fault exists in the platform area, and judging whether the residual current value of each user side is larger than a second threshold value of 30mA or not;
If not, determining that only electric leakage of the power transmission line exists in the transformer area; if yes, judging whether the difference value between the residual current value of the platform area and the total residual current value of the user side is larger than a third threshold value of 100mA or not;
If not, determining that only the electric leakage of the user side exists in the platform area; if yes, determining that the electric transmission line electric leakage and the user side electric leakage exist in the transformer area at the same time.
