Description
Technical field
The utility model relates to a kind of debug system, particularly relates to the test of a kind of intelligent substation message emulating and correlation analysis system.
Background technology
IEC61850 is that TC57 working group of International Electrotechnical Commission is for " substation communication network and the system " series standard solving the up-to-date formulation of interoperability issue that electric substation automation system faces, it is the substation network communication system of the unique a new generation in the whole world, adapt to IED and the electric substation automation system of layering, for the general layout of " unified standard, unified model, the interconnected opening " of Automation of Electric Systems product is laid a good foundation.This standard obtains the support of domestic and international most of main flow producer, becomes the global information interaction standard unified in power system transformer substation automatic field.
Formulation gradual perfection from 2000 of IEC61850 standard.Experienced by the research of nearly more than ten years, study and exploration, the Intelligent transformer station set up based on this standard reaches its maturity, and the construction of Intelligent transformer station will enter the Fast Growth stage.
The introducing of IEC61850 standard makes by special data communication network, becomes possibility with the information exchange of the model of standard between different manufacturers, dissimilar smart machine.But because of the discrepancy that different manufacturers is understood standard, communication or smart machine failure and other reasons, add complicated primary fault condition, be easy to cause in information exchange and error on intelligent electronic device (IED) self processing logic, thus cause the consequence that cannot expect or make system responses accomplish optimum.Utilize traditional relay testing, debugging acid, means and method, the system-wide situation of unable real simulation, the response of system to some failure and special conditions is become and is difficult to prediction, also there is test simultaneously, debugging cycle is long, the problems such as result is unreliable.Same problem also appears in the routine inspection of electrical secondary system and observation process, thus the hidden danger of unable Timeliness coverage system is caused, hamper the raising of system operation reliability, therefore release one containing complete numeral and the hybrid simulation of physics secondary device and the intelligent substation simulating experimental system of measuring ability, there is very major and immediate significance and application prospect.
Adopt the transformer station of IEC61850 standard traffic, the mutual message between smart machine has three kinds usually:
GOOSE(Generic Object Oriented Substation Events) message, and general OO transformer substation case message.Mainly be used for send state and state change information, state variation is referred to as event.
SMV(Sampled Measured Value) message, and sampled measurement message.Be mainly used to the electric parameters that transmission sensing acquisition arrives.
GOOSE message and SMV message are based on two layers of transmission, and the general mode of multicast that adopts is propagated.Message sends fast and stable.Except these two kinds, also has MMS message.
MMS (Manufacturing Message Specification) is a set of international standard message specification for developing and safeguard industrial automation system formulated by International Organization for standardization ISO.MMS specification industrial circle has the communication behavior of the intelligent sensor of communication capacity, intelligent electronic device, intelligent control device, uses and have interoperability between the equipment of different vendor, the system integration is become simply, convenient.IEC61850 standard absorption also applies manufacture message specification MMS, by carrying out the method for modeling to real equipment and function thereof, realize the real-time exchange of data and monitor message between computer applied algorithm under network environment or intelligent electronic device IED (Intelligent Electronic Device).MMS is widely used in remote control equipment, equipment oneself state and the non-electric quantity information collected.
Along with the promotion and application gradually of digitlization/Intelligent transformer station, IEC61850 communication is widely used in electric substation automation system.In system, device interactive mode changes, and the association between device is set up by the message switching of networking, but not by the numerous and diverse of past but clearly physical connection is set up.This simplifies system wiring on the one hand, adds the global reliability of system, brings new challenge to but then the commissioning of transformer station.
Compared with digitlization/intellectualizing system, traditional interactive mode is linked together by the device needing to intercom mutually by cable, uses electric analog information transfer signal; The association of device can be known clearly by on-site cable connection.After digitlization, device interactive mode is linked together by all devices by fiber optic network, with above-mentioned three kinds of message transmission of informations; All intercommunications mutually or the device do not communicated all connect in a network, and the logic association relation of device cannot know clearly from physical connection.
And the logic association relation of device in digitlization/intellectualizing system, by Substation Configuration Language (SCL) model description, be recorded in substation configuration description (SCD) file.But whether the device be difficult at present in verification whole system intercoms mutually according to the association configured in SCD, and device communication process and step are also unclear.For the intelligent electronic device for system protection widely used in digitlization/Intelligent transformer station; general relay testing instrument tends to set up man-to-man interconnection with tested device; lack whole system configuration information, cannot entire system response be recorded and be checked.Be difficult to efficiently test protection, the interlock reciprocal process in intelligent substation between each device cannot be analyzed.
Real-timedigital simulation technology (RTDS) application in electric power system is the operation digital technique of the relative maturity of development.But the main target of emulation is the response of primary system to various electric condition.For intelligent substation, a full-order system, combines by first and second and coordinates generation.Based on this; need to transform traditional analogue system based on RTDS; become a hybrid simulation environment of compatible with digital emulation and actual physical IED equipment; thus allow analogue system can simulate a various electric condition and observe the response of physical I ED equipment under these conditions, be used for doing accurate judgement to the necessary protection setting of system, relay protective scheme.
But analogue system itself is especially mixed with the analogue system of physical I ED, because cannot record the response of involved whole secondary devices comprehensively, only possesses limited data analysis capabilities.For accomplishing the understanding response in whole system being had to panorama type, usually also need to be aided with the various recording assay device comprising fault fluid parameter, make the configuration of whole system, coordinate seem too numerous and diverse, add to result understand analyze difficulty.
The analyzing network communication record system for IEC61850 electric substation automation system in the past, can only according to the deciphering to system configuration, carry out simple, the isolated form judging message and whether meet configuration, rapid analysis cannot be carried out to correlation between the message that represent system under test (SUT) service logic.Simultaneously system and method in the past lacks the simulation capacity to intelligent apparatus interface, thus extremely affects test, analysis efficiency and result.
