Problems solved by technology

However, this kind of power distribution structure cannot complete the task of fault isolation, let alone the task of automatic restoration of power supply, only relying on microcomputer relay protection. Only a distribution automation system suitable for the characteristics of this power distribution structure will do
[0004] Although the current distribution automation system can complete the fault handling of the opening and closing station of the ring network, it must rely on communication and distribution master stations or sub-stations, the system is huge, installation and maintenance are difficult, and it is difficult to replicate and promote

Embodiment 1

[0023] Embodiment 1: see figure 1 ,Such as figure 1 As shown, a switching station fault handling system can have up to 255 switching station fault processing subsystems 2 and a set of data monitoring system 1, each switching station fault processing subsystem 2 is installed in each switching station, using GPRS The relevant information is sent to the Internet network 3, and the data monitoring system 1 receives information from the Internet network 3, communicates with the information receiving device 4 through GSM in the form of a short message, and informs relevant personnel of relevant fault information.

[0024] The fault line current value, fault time, switch status, etc. can be viewed in the fault processing subsystem 2 of each switching station and the data monitoring system 1 .

Embodiment 2

[0025] Embodiment 2: below with figure 1 and figure 2 Combined as an example to illustrate the present invention's processing of various faults, assuming that the flow direction is as follows figure 2 In the direction of the arrow:

[0026] Intelligent processing process of circuit breaker feeder short-circuit fault: when d1-1# switching station 102DL circuit breaker feeder short-circuit fault, figure 1 The failure processing subsystem of the 1# switching station issues an order to make figure 2 The 102DL circuit breaker of the 1# switching station in the middle tripped in 0 seconds, and the fault was isolated; figure 1 The fault handling subsystem of the middle 1# switching station uses GPRS communication to send relevant information to the Internet network, the data monitoring system receives information from the Internet network, and the data monitoring system sends the "1# switching station 102DL circuit breaker feeder Fault, Fault has been isolated" and other relev...

Abstract

The invention discloses an HP-9000 type switching station fault treatment system, which comprises a plurality of switching station fault treatment subsystems and a set of data monitoring system, wherein each switching station fault treatment subsystem is arranged in each switching station, all the switching station fault treatment subsystems are communicated with the data monitoring system by the internet network, and the data monitoring system is communicated with an information receiving device in a GSM (global system for mobile communications) short message mode. According to the HP-9000 type switching station fault treatment system, the positioning and isolation of various types of faults of the cascading switching stations and the automatic recovery of power supply in a non-fault area can be realized without communication, the override trip accident can be avoided, the faults that an incoming line, a bus, a feeder line of the switching station power source are return circuits of a circuit breaker, the feeder line is the return circuit of a load switch and abnormal override trip exists can be isolated and treated, and the automatic recovery of power supply is realized in a fault area; and if a switching station is failed, a related person is informed by the system through a short message so as to accelerate the fault maintenance.

Description

1. Technical field: [0001] The invention relates to a fault processing system, in particular to a HP-9000 switching station fault processing system, which belongs to the field of power distribution automation. 2. Background technology: [0002] In recent years, with the rapid development of my country's economy, urban construction is also changing with each passing day, and the construction of corresponding power supporting facilities is also indispensable. In order to ensure the reliability of power supply, the electric power departments of large and medium-sized cities have basically adopted the primary power distribution structure of multi-power switching and ring network power supply in the new construction and renovation projects of the 12kV distribution network, and the primary main wiring adopts a single Most of the mother section. [0003] The operation mode of this power distribution structure is flexible, which reduces the time and scope of power outages due to fa...
