All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Referring to fig. 1 in combination, fig. 1 is a schematic flow chart of a first embodiment of a bypass simulation method for a power transmission line according to the present application. The bypass simulation method of the power transmission line provided by the application comprises the following steps:
s101: the method comprises the steps of obtaining a target maintenance circuit, constructing a bypass simulation circuit according to the target maintenance circuit, wherein the bypass simulation circuit comprises two groups of simulation varistor groups, each group of simulation varistor groups comprises at least two simulation varistors with adjustable resistance values, and two ends of each group of simulation varistor groups are connected with a simulation power supply.
In one particular implementation scenario, a target repair circuit is obtained, which may be a section of a transmission line or an entire section of a transmission line. And constructing a bypass simulation circuit according to the target maintenance circuit. Referring to fig. 2 in combination, fig. 2 is a schematic structural diagram of an embodiment of a bypass simulation circuit according to the present application. As shown in fig. 2, the bypass circuit 10 includes two simulated varistor groups 11 and 12, one on each leg of the bypass circuit.
The simulated varistor group 11 comprises two simulated varistors 111 and 112 of adjustable resistance connected in series, the simulated varistor group 12 comprises two simulated varistors 111 and 112 of adjustable resistance, in other implementation scenarios the simulated varistor groups 11 and 12 may comprise a greater number of simulated varistors, but the number of simulated varistors in the simulated varistor groups 11 and 12 is equal. In other implementations, each set of simulated varistors includes the same number of simulated varistors as the number of preset repair segments of the repair target repair circuit. The number of the preset maintenance sections of the target maintenance circuit can be obtained in advance, and the number of the varistors of each group of the simulated varistors is set to be the same as the number of the sections
Two ends of the two groups of simulated varistors 11 and 12 are connected to a simulated power supply, and in this embodiment, two ends of the two groups of simulated varistors 11 and 12 are connected to a 35kV power supply. In other implementation scenarios, the voltage of the simulation power supply is designed according to the actual application requirements, and the simulation power supplies connected to the two ends of the two groups of simulation varistor groups 11 and 12 may be equal or unequal.
S102: the change in current and/or voltage of the bypass simulation circuit is monitored by a monitoring device connected to the bypass simulation circuit.
In a specific implementation scenario, a monitoring device is connected to the bypass simulation circuit, where the monitoring device may be a device for measuring circuit parameters such as current, voltage, resistance, and the like, and the monitoring device may measure circuit parameters corresponding to each simulation varistor, or measure circuit parameters corresponding to each group of simulation varistors, and may also measure circuit parameters of the bypass simulation circuit, and may be set according to practical application requirements.
S103: and sequentially changing the resistance value of each simulation rheostat according to a preset sequence, and obtaining the real-time value of the current and/or the voltage of the bypass simulation circuit when the resistance value of each simulation rheostat is changed.
In a specific implementation scenario, the resistance of each simulated varistor is sequentially changed according to a preset sequence. The preset sequence may be plural, for example, plural kinds of sequences such as 111, 112, 121, 122, 121, 111, 121, 122, 111, 112, 122, 121, and the like will be preset. Further, the preset sequence further includes two sequences of changing the resistance value of each simulated varistor from 0 to infinity and from infinity to 0, for example, first changing 111 and 112 from 0 to infinity and then changing 121 and 122 from infinity to 0. The specific preset sequence is designed according to the actual maintenance requirement.
When the resistance value of each simulation rheostat is adjusted to change, the resistance value needs to be adjusted within preset time, the preset time is determined according to actual maintenance requirements, and the preset time is less than or equal to 5s in the application because the simulation rheostat needs to be quickly connected or disconnected during daily maintenance.
S104: and acquiring the safety sequence of the change simulation rheostat according to the real-time numerical value.
In a specific implementation scenario, the real-time value of each simulated varistor is detected and whether the real-time value is within a safe range is determined, and the safe range can be preset. And if the real-time numerical value is in the safety state, taking the preset sequence as the safety sequence. And if the real-time value is not in the safety state, generating an adjustment sequence according to a preset sequence adjustment scheme, taking the adjustment sequence as the preset sequence, and executing the step of judging whether the real-time value of the current and/or the voltage of the bypass simulation circuit is in the safety state or not when the resistance value of the simulation rheostat is changed according to the preset sequence until the real-time value is in the safety state, and obtaining the safety sequence.
For example, in the application scenario shown in fig. 2, the preset sequences are 111, 112, 121, and 122, if the real-time value is in the safety range when the resistance value of 111 is adjusted, the resistance value of 112 is adjusted according to the preset sequence, if the real-time value exceeds the safety range when the resistance value of 112 is adjusted, the test is stopped, the adjustment sequence is generated according to the preset sequence adjustment scheme, for example, 112, 121, and 122, the steps are repeated according to the new adjustment sequence until all the simulated varistors are adjusted, and the real-time value is always in the safety range, and the preset sequence is used as the safety sequence. The preset sequence adjustment scheme can be to exchange the front-back sequence of at least two simulation varistors in the original preset sequence, and ensure that the generated adjustment sequence is different from all the previous preset sequences. For example, the preset sequence is 111, 112, 121, 122, the real-time value is in unsafe state, the adjustment sequence is 112, 121, 122, the real-time value corresponding to the adjustment sequence is still in unsafe state, and if the adjustment sequence is 111, 112, 121, 122, the preset sequence is the same as the previous preset sequence, the adjustment sequence is not used, and the adjustment sequence is 112, 122, 121 different from the previous preset sequence.
When the power transmission line is maintained actually, the preset maintenance sections of the power transmission line are disconnected or connected according to the safety sequence, so that the safety of maintenance personnel is ensured.
In other implementations, after the safety sequence is acquired, an actual bypass circuit of the target repair circuit is constructed according to the bypass simulation circuit, and the target repair circuit and the actual bypass circuit are cut off and/or connected according to the safety sequence to repair the target repair circuit. Specifically, if the resistance value of the simulation rheostat is adjusted from 0 to infinity, the corresponding operation of disconnecting the preset maintenance section corresponding to the simulation rheostat is performed, and if the resistance value of the simulation rheostat is adjusted from infinity to 0, the corresponding operation of connecting the preset maintenance section corresponding to the simulation rheostat is performed.
