S100, acquiring the working status of all the bay devices in the power system.

In the power system, the substation is composed of some closely connected parts with some common functions. For example: switchgear between incoming line or outgoing line and busbar; busbar connection device composed of circuit breaker, isolating switch and grounding switch; switchgear related to transformer and busbars of two different voltage levels. The primary circuit breaker and related equipment are formed into virtual bays. These parts constitute a protected sub-part of the power system, such as a transformer or one end of a line, corresponding to the control of switchgear, with certain common constraints, such as interlocks or well-defined sequences of operations. The bay equipment is all the equipment in the bay, such as circuit breakers and isolation switches, and the working state refers to whether the circuit breaker is closed or open, and whether the isolation switches are closed or open. This embodiment does not impose any limitation on the method for acquiring the working states of all the bay devices in the power system.

In a specific embodiment, a current transformer can be used to obtain the current of the bay equipment in each of the connected systems, or a voltage transformer can be used to obtain the voltage of the bay equipment in each of the connected systems.

S320, according to the electrical quantity of the bay device in each of the connected systems, determine whether the bay device in each of the connected systems is faulty.

By judging or comparing the obtained electrical quantities of the bay devices in each of the connected systems, it is determined whether the bay devices in each of the connected systems are faulty. Specifically, if the obtained electrical quantity is current, it can be determined whether the current has changed significantly in a period of time to determine whether the interval equipment in each of the connected systems is faulty; or The current is compared with a preset current threshold to determine whether the bay equipment in each of the connected systems is faulty. This embodiment does not impose any limitation on the method for determining whether the partition device in each of the connected systems is faulty according to the electrical quantity of the partition device in each of the connected systems.

In one embodiment, the first preset condition is at least one of less than or equal to a preset instantaneous value, greater than or equal to a preset change amount, and greater than or equal to a preset change rate.

The preset instantaneous value may be a voltage instantaneous value preset by the operator, which may be expressed as u _zd . When the acquired instantaneous value of the voltage is less than or equal to the preset instantaneous value, that is, u _t ≤u _zd , it is determined that the interval equipment in the connected system is faulty. The preset change amount may be a voltage change amount preset by the operator, which may be expressed as S _Uzd . When the acquired voltage variation is greater than or equal to the preset variation, that is, S _u ≥ S _Uzd , it is determined that the interval equipment in the connected system is faulty. The preset rate of change may be the rate of change of voltage of the staff's pre-equipment, which may be expressed as ν _Uzd . When the acquired voltage change rate is greater than or equal to the preset change rate, that is, ν _u ≥ ν _Uzd , it is determined that the interval device in the connected system is faulty. In a specific embodiment, the instantaneous value of the voltage of one bay device in the connected system may be less than or equal to the preset instantaneous value, and the voltage variation of another bay device in the connected system may be greater than or equal to The preset change amount; it may also be that the instantaneous value of the voltage of an interval device in the connected system is less than or equal to the preset instantaneous value, and the voltage change amount is greater than or equal to the preset change amount, the connected The voltage change amount of another interval device in the system satisfies the preset change amount or more, and the voltage change rate satisfies the preset change rate or more.

S410: Determine whether the electrical quantity of each bay device in each of the connected systems satisfies the second preset condition.

S420. If the electrical quantity of each bay device in each of the connected systems satisfies the second preset condition, the fault type is the primary system fault.

S430, otherwise the fault type is the secondary system fault.

The second preset condition may be a judgment condition preset by the staff according to the actual situation. This embodiment does not impose any limitation on the second preset condition, as long as its function can be realized. The fault type of each of the connected systems is determined by judging whether the electrical quantity of each bay device in each of the connected systems satisfies the second preset condition. If the electrical quantity of each bay device in one of the connected systems satisfies the second preset condition, then the failure type of the connected system is the primary system failure, otherwise the failure type of the connected system for the secondary system failure.

In one embodiment, the electrical quantity is a voltage parameter, wherein the voltage parameter includes a voltage instantaneous value, a voltage change amount, and a voltage change rate, and the second preset condition is less than or equal to a preset instantaneous value, greater than or equal to Either the preset change amount or the preset change rate is greater than or equal to.

That is, each interval device in each of the connected systems may satisfy the condition of being less than or equal to the preset instantaneous value, may also satisfy the condition that is greater than or equal to the preset change amount, or may all satisfy the condition of being greater than or equal to the preset change amount. The condition is greater than or equal to the preset rate of change. If the instantaneous value of the voltage of a bay device in one of the connected systems is less than or equal to the preset instantaneous value, and the voltage variation does not satisfy the predetermined change or greater, and the other bays in the connected system If the instantaneous value of the voltage of the device is not less than or equal to the preset instantaneous value, and the voltage variation is greater than or equal to the preset variation, it means that the fault type of the connected system is the secondary fault.
