Description
Technical field:
The present invention relates to transforming plant protecting measurement and control integration technology, belong to protecting electrical power system and monitoring technique field based on many agencies (Agent).
Background technology:
Along with power system development, protection and observing and controlling have realized microcomputerization and automation basically, have also occurred some problems simultaneously:
(1) quite a few hardware device and function being arranged is repetition, but the equipment of these repetitions and function can not be mutual
For standby, caused the waste of resource.Need line current as route protection, bus protection and metering dress
Putting also needs line current, and they are repetitions to soft, the hardware of line current collection, because these dresses
It is separate putting, and making has repetition but can not be standby mutually.
Cooperating between (2) high pressure, superhigh pressure transforming plant protecting and protection, protection and the automatics is quite complicated, and
And there is the long problem of backup protection setting time; Gu Ding definite value can't adapt to system in some cases
The dynamic change of system, adaptive guard can be adjusted protection according to the operation of power networks state, but it is required
Want bulk information to be difficult to obtain (list of references 1).
(3) existing Microcomputer Protection seriously is subjected to traditional analog protection thinking to fetter the intelligence of computer and network on algorithm
Effect is not fully used; In configuration, still too focus on isolated " element protection " function
Itself, interchange and coordination between the famine " element protection "; Examining aspect data sharing and the analysis
Consider less (list of references 8).
(4) protection and automatics from different manufacturers, use different soft, hardware platform, between them soft,
Hardware is not general and swap data is difficult, and this has not only reduced flexibility in actual use, and not
Be convenient to the exploitation of new product.
(5) though occurred some so-called protection measurement and control integration devices now, protect as the DSA transformer station that south is auspicious
Protect the measurement and control integration system, but just in local implementation the protection measurement and control integration, as logical for transformer
Cross a device and realize, and be relatively independent between each integrated unit its protection, measurement and control

Embodiment:
The protection measurement and control integration system hardware of whole transformer station is made of many microcomputers and LAN system, and software is realized in modular mode on the Aglet of IMB company Agent platform with the JAVA language according to actual needs.
(1). the multi-Agent data acquisition system.Use analog quantity and digital quantity (switching value) acquisition hardware to utilize GPS that all analog signalses, switching value signal are carried out synchronized sampling; sample rate is selected 2-10KHz for use; the hardware that such sample rate is general can satisfy, and to adopting advanced protection algorithm also favourable.Acquisition hardware and software adopt unified interface, make just to can be applicable to data acquisition system as long as acquisition hardware and corresponding Agent satisfy certain technical specification, accomplish to gather and hardware independent.Intelligence by gathering Agent and the mutual linkages and communication between the collection Agent are finished the anti-interference error correction to sampled data.The data of gathering are given data and are preserved Agent, the fast reading and writing that it is responsible for preserving the data of certain hour (several to dozens of cycles) in internal memory and finishes data.Data issues Agent in the mode of broadcasting to distributing data, for protection, measurement and control system use.Distributing data is issued in the mode of not compressing.If transformer station needs 100 analog channels, each passage 16bit sampling, sample rate 5kHz, these data rates of broadcasting are not 100 * 16 * 5/8=1000kByte/s=1M Byte/s=8MBit/s (not comprising the nested word of communications protocol etc.) with compressing, present Ethernet can reach 100,000,000 to gigabit Bit/s speed, such distributing data speed is less for the pressure of network, therefore can issue in the mode of not compressing.If passage is a lot,, can adopt the mode distributing data of compression for fear of network congestion.Because whole transforming plant protecting measurement and control integration system based on multi-Agent realizes on local area network (LAN), so network is the hardware core of whole transforming plant protecting measurement and control integration system based on multi-Agent.Therefore each link of network all is dual or multiple, and a place or many places fault still can provide correct data to other Agent system in the assurance system.
(2). the multi-Agent protection system.Protection no longer has been a hardware, but the software of forming by a plurality of Agent.All protections move on a unified Agent platform, and exchange message no longer is to realize by the hardware line between " element protection " and other protection and the device, but realizes by communication mechanism on the Agent platform.The implementation method of multi-Agent protection system can be used for reference the thought of present Microcomputer Protection " element protection "; by multi-Agent its protection algorithm is realized; make up relatively independent " element protection ", can reach than the better effect of existing Microcomputer Protection by communication between the protection.Not available characteristics of traditional Microcomputer Protection such as the cooperation between the autonomy of Agent, reactivity, initiative and the Agent, cooperation, coordination in addition; make the multi-Agent protection system can break the notion of isolated in the past " element protection "; set up organic, a whole transforming plant protecting system; thereby can seek the new approaches that the intelligence of utilizing Agent is protected transformer, bus, circuit, circuit breaker etc., reach the responsiveness (particularly backup protection) that improves protection on the whole and the purpose of raising reliability.The multi-Agent protection system realizes (referring to Fig. 2) in the mode that distributes, and one side can guarantee the reliability protected even there are one or more hardware to break down, also to be unlikely to make protection system not work like this; Load that on the other hand can the reasonable distribution computer and make full use of the disposal ability of each computer.
(3) .Agent measuring system.Different with existing measuring unit, it self does not have data division, but is undertaken by the data that receive the data acquisition system issue that computing measures.Because measured intelligence and the interaction capabilities that suitable redundancy and Agent are arranged, measurement means such as multi-Agent measuring system user mode estimation improve precision and the reliability of measuring.
(4). the multi-Agent control system.Utilize the increase greatly of intelligence and the amount of information of Agent, improve the reliability and the degree of intelligence of protection and automatics.
(5) multi-Agent management system.Make up friendly and perfect Management Agent system, by Management Agent can be easily to operation such as protecting, observing and controlling Agent add, deletes, revise its parameter and finishing and the exchanges data of scheduling, centralized control center.
