Compared with the prior art, the utility model can be applied to all the microcomputer protection devices, also can provide the functions of visual detection and accident inversion, and can improve failure query efficiency by 60 percent.
Description
Technical field
The utility model relates to a kind of device of technical field of power systems, specifically is a kind of electric power system Microcomputer Protection on-line condition monitoring device.
Background technology
Requirement according to DL/T995-2006 " relaying protection and power grid security automatics check regulations "; periodic inspection is carried out in relaying protection, automatic safety device and secondary circuit wiring; to guarantee that device element is intact, function is normal, guarantee that circuit connection and definite value are correct.Microcomputer protecting device self has its powerful self-checking function; but the application to these numerous self check information only limits to information such as protective device is unusual, power failure, TA/TV broken string at present; and a large amount of components and parts and logical circuit node status information fail effectively to use; the one, there are not reliable means to obtain these information, the 2nd, method does not go to represent these information intuitively.
Find through retrieval prior art; " relaying protection repair based on condition of component and enforcement are inquired into " (relay; the 33rd the 20th phase of volume; on October 16th, 2005) speak of in the literary composition to the protection repair based on condition of component; utilize the collection that realizes protection control loop state into contact of opening of SEL protective device; and the logical equation by the SEL protective device and relay leave and realize anti-jump function, adopts above-mentioned guard mode monitoring technology to reach the target of guard mode maintenance.
But the prior art only realizes the collection of state to the control loop beyond the protective device; and be only applicable to have the protection (as SEL) of PLC function, monitor and a large amount of components and parts of protective device self and logical circuit node status information be difficult to leave by logical equation and relay.
The utility model content
The utility model provides a kind of electric power system Microcomputer Protection on-line condition monitoring device at the prior art above shortcomings, realizes the state in-service monitoring to protection logical circuit node and various components and parts, to reach the on-line fault diagnosis to protective device.
The utility model is achieved through the following technical solutions, the utility model comprises: microprocessor, Ethernet card, bus control unit, Programmable Logic Controller, maintenance interface controller, power supply, system clock and storage control, wherein: microprocessor is connected with bus control unit, maintenance interface controller, Ethernet card and system clock respectively, and Programmable Logic Controller, storage control and power supply are connected with microprocessor respectively successively by bus control unit.
This state monitor is realized visual protection on-line condition monitoring; mainly by Programmable Logic Controller by device oriented protection philosophy modeling; realize the logical mappings of physical equipment and the visual expression of logical circuit of protection philosophy, model parameter contains variablees such as related control bit of equipment tropism, components and parts, logic function and state value.
The utility model can be applicable to all microcomputer protecting devices compared to existing technology, and visual measuring ability and accident inverting function can be provided, and can improve 60% to fault inquiry efficient.
