Description
Technical field
The present invention relates to equipment for monitoring power quality product control technical fields, and in particular to a kind of realization electric energy quality monitoring dress
Set multiple services system and method.
Background technique
Electric energy quality monitoring system generallys use equipment for monitoring power quality (or terminal)-main website two-layer structure at present,
Communication protocol between equipment for monitoring power quality and main website now uses Modbus, PQDIF, IEC61850 specification, and
IEC61850 specification model data amount is big, classification is more, definition is than broad, because of the research and development people of each equipment for monitoring power quality producer
Member has a certain difference the understanding of IEC61850 specification, causes the equipment for monitoring power quality communication protocol of each producer random
It is larger, need to be to equipment for monitoring power quality integrated test, but inspection producer device model is more, specification accuracy test project is more, work
Work amount is big, can only concentrate development annual at present.Since each equipment for monitoring power quality producer is without corresponding protocol convert ring
Border, the equipment for monitoring power quality that the supply of material is installed on substation not can guarantee the consistency of its communication protocol, need constantly to adjust
Examination program could smoothly access main station system, can not achieve real plug and play, this debugging during put into a large amount of manpower and
Time cost.The communication network presence of newly-built substation is not installed, substation to main website is related to the open-minded of multiple tracks firewall
Etc. a variety of possibility, there are more difficulties for equipment for monitoring power quality and Master station access joint debugging, since equipment for monitoring power quality has
There is the characteristics of large number of, installation dispersion, there are many deficiencies for existing product control measuring technology method, and if according to existing skill
Art carries out protocol convert to equipment for monitoring power quality, is necessarily required to put into great man power and material, therefore realizability is poor,
So that the monitoring device for being installed on substation is difficult access system, the waste of entire society's resource is caused.
The operational management of equipment for monitoring power quality is one of the action of power quality technical supervision.Power quality prison
Survey after device runs for a long time in severe electromagnetic environment, inevitably can due to component aging, failure and lead to device can
Decline by property, accuracy of measurement, and then generate a large amount of invalid, abnormal datas, it is therefore desirable to which periodic detection is carried out to it.Currently,
Equipment for monitoring power quality detection is normally based on standard source method to realize, and there are mainly two types of implementation: 1, will be electric
Energy quality monitoring device, which removes, is sent to laboratory, then controls standard source and exports specified signal to equipment for monitoring power quality, most
The measurement result of equipment for monitoring power quality is obtained afterwards, to judge whether the accuracy of measurement of the equipment for monitoring power quality closes
Lattice need out multiple work ticket its shortcoming is that equipment for monitoring power quality is dismounted back and forth, and transport trouble, time-consuming, make in addition
It must complete an inspection and need to expend longer time, working efficiency is low, is seriously affecting equipment for monitoring power quality just
Often work；2, standard source is carried to scene, equipment for monitoring power quality is removed into carry out on-site test, its shortcoming is that mark
The quasi- usual volume in source should not carry greatly, and instrument is very accurate to be easily damaged, and also need to carry several standard sources structure together sometimes
It is detected at a three-phase circuit.Since equipment for monitoring power quality has the characteristics that large number of, installation dispersion, if according to
The prior art carries out periodic detection to it, is necessarily required to put into great man power and material, therefore realizability is poor, so that periodically
Detection work is difficult to effectively carry out.
In conclusion there are many deficiencies for the prior art, it is seen then that it is necessary to study a kind of easy to use, reliable satisfactions
Specification detection, the monitoring analysis, on-the-spot testing method and system of equipment for monitoring power quality, greatly simplify communication protocol consistency
Detection difficulty, while incorporating electric energy quality monitoring analytic function, the on-the-spot testing detection for reducing equipment for monitoring power quality is difficult
Degree improves power quality working efficiency, while reducing cost of human and material resources, so that the generaI investigation of equipment for monitoring power quality is surveyed
The work such as examination, on-the-spot testing, equipment for monitoring power quality access main station system can effectively be carried out, veritably by power quality skill
Art supervision work is fulfilled, and is escort for safe and stable, the economical operation of power grid.
