Description
Technical field
The present invention relates to a kind of equipment for monitoring power quality model, belong to the electric intelligent technical field of automation based on IEC61850.
Background technology
Networking, informationization, standardization and the intelligent inevitable development trend that has become electric energy quality monitoring system; But existing monitoring equipment extensively adopts the self-defined communication protocol of producer; The standard of following is also inconsistent; Cause occurring in the monitoring net process of construction poor compatibility between the devices from different manufacturers, data sharing difficulty, problem such as the distributed-network monitoring platform operational efficiency is low.Adopt the power quality data DIF of PQDIF standard in the existing part monitoring system as a kind of standard; It has solved the problem how data between the different quality of power supply file formats exchange storage; But consider actual power quality-monitoring needs, need to consider many aspects such as historical data, real time data, SOE incident, Wave data in the observation process, the PQDIF file has big limitation aspect processing real time data, the transient event; Simultaneously; Data Format Transform needs interface routine to realize, numerous interface routines is that system brings stable hidden danger, and management cost.For guaranteeing the data compatibility between distinct device; Directly the slave unit aspect solves the data compatibility problem becomes a kind of necessary; Particularly along with the popularization construction of intelligent substation, the exploitation that the IEC61850 standard is incorporated into power quality monitoring device becomes a kind of inexorable trend.
Summary of the invention
The objective of the invention is, for guaranteeing the data compatibility between distinct device, solve the data compatibility problem, the present invention discloses a kind of equipment for monitoring power quality model based on the IEC61850 standard.
Technical scheme of the present invention is, said model is divided into by function that steady state data is measured, transient event detects with equipment for monitoring power quality and three types of monitor logs, describes respectively through the different logical node; Said steady state data is measured the logical node that adopts among the logical node group M; Said transient event detects the logical node that adopts among the logical node group Q; Can trigger logical node RDRE in the said monitor log and be used for carrying out waveform recording, logical node LPHD is adopted in operational monitoring; The monitoring real time data adopts the form of report to realize that time recording data, event log data usage log are stored.
The described quality of power supply relevant information of the inventive method has then directly adopting of corresponding model in the IEC61850 standard; Then do not adopt interrelated logic node or related data object to expand realization if having; Wherein remote control record ripple, remote control control such as reset realizes through the SPC object of GGIO logical node, object oriented be followed successively by SPCSO1, SPCSO2 ...Whether the former limit of voltage, voltage time limit, the minimum capacity of short circuit of voltage, power voltage supply place capacity, voltage User Agreement capacity, voltage are that configuration information such as points of common connection is employed in and expands the value data object among logical node zero LLNO; Object type is according to the type classification of value; As adopting ASG for floating number; As be that integer then is ING; And the title of data object adopts self-defining mode, is defined as " DyOrEdge ", voltage time limit like the former limit of voltage and is defined as " DySeEdge ", the minimum capacity of short circuit of voltage and is defined as " DyMSC " etc.
In the IEC61850 standard, model is as to the map of actual physics device, the method for its modeling and as shown in Figure 1 with the relation of standard each several part.To the actual IED in the transformer station, through logical abstraction, be divided into minimum entity-logical node LN by function, as: MMXU describes the fundamental measurement amount, and it has comprised data object relevant with its function such as PhsPhsV (line voltage) down again.Logical node according to close function combinations to forming logical device together; Realize concrete model description through the defined substation configuration description language of IEC61850-6; Abstract Common Service Interface (ACSI) through IEC61850-7-2 definition is set up service model, transmits through the TCP/IP network being mapped as MMS (manufacturing message specification) message through specific communication map of services (SCSM).
The equipment for monitoring power quality model modeling comprises: the modeling of quality of power supply logical node, data object and data attribute modeling, logical device modeling.
Equipment for monitoring power quality is mainly monitored circuit according to the GB related request.According to the demand of GB requirement and practical power systems, equipment for monitoring power quality has mainly comprised following index: the permissible variation of supply power voltage, voltage fluctuation and flicker, imbalance of three-phase voltage degree, mains by harmonics etc.The concrete manifestation of different quality of power supply incidents is a power quality index, and therefore, different power quality indexs has just formed the logical node instance.
IEC61850-7-4 has defined a plurality of logical nodes and has described quality of power supply partial information, measures logical node (MMXU), mainly is used for describing the information of basic Monitoring Line, like voltage, electric current, power etc.; Preface component logical node (MSQI), the electric current and voltage amount of description positive sequence, negative phase-sequence and zero sequence; Harmonic content logical node (MHAI) is described like each harmonic voltage, electric current, harmonic content etc.
But above logical node can not satisfy the needs of practical application far away to the description of quality of power supply correlation function, therefore, need expand logical node, to accomplish the description to relevant power quality index.
The present invention has defined the logical node model of quality of power supply correlation function.Like flickering logical node (MFLK), be used to describe flickering in short-term, flickering etc. when long; Voltage deviation logical node (QVVR) is described the change in voltage incident; Frequency departure logical node (QFVR) is in order to describe the frequency change dependent event; Voltage unbalance degree logical node (QVUB) is in order to describe Voltage unbalance degree and dependent event.The equipment for monitoring power quality model structure is as shown in Figure 2.
The beneficial effect of the present invention and prior art comparison is; The present invention proposes a kind of equipment for monitoring power quality model, only equipment for monitoring power quality is divided by function, be divided into that steady state data is measured, transient event detects and three types of monitor logs based on the IEC61850 standard; Describe respectively through the different logical node; Can simplify the structure of electric energy quality monitoring system, reduce and build and maintenance cost, increase autgmentability.
The present invention is applicable to the intelligent substation electric energy quality monitoring.
