Net.
Advantage of the present utility model and good effect be:
This utility model uses wireless mode to be sent to far by the harmonic data being arranged on distributed photovoltaic monitoring point
The host computer of journey, solves the demand to distributed photovoltaic electric energy quality monitoring during present stage power network development,
For solving distributed photovoltaic access system, the impact of the electrical network quality of power supply is provided effective tool, be conducive to dividing
The dynamic operational behaviour of power system under analysis complex electric network network environment, for improving grid supply quality, improves wind
Group of motors manufactures and designs and parameter tuning, strengthens the operational reliability of electrical network, it is provided that reference frame.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
In figure, 1-Detecting Power Harmonics module；2-wireless transport module；3-data line；4-wireless antenna.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model embodiment is further described:
A kind of distributed photovoltaic harmonic wave on-Line Monitor Device, as it is shown in figure 1, include the humorous of casing and inside thereof
Ripple monitoring modular 1, wireless transport module 2, data line 3, casing is provided with wireless antenna and with
Wireless transport module is connected, and described Detecting Power Harmonics module is connected with wireless transport module by data line
Connecing, data line can use RS232, RS485 connection, i.e. Detecting Power Harmonics module and be wirelessly transferred mould
Block uses RS232 or RS485 mode to carry out data transmission.
This utility model is arranged on distributed photovoltaic position, monitors distributed light in real time by Detecting Power Harmonics module
Detecting Power Harmonics module monitors data are transferred to nothing by RS485, RS232 transmission means by the Harmonic Conditions of volt
Then data are passed back electrical power mains data network by wireless antenna and are unified by host computer by line transport module
Processing, wireless transport module can be used GSM, GPRS and be carried out data transmission by wireless network.
Distributed photovoltaic harmonic wave on-Line Monitor Device being arranged at different distributed photovoltaics, each is supervised online
Surveying device and the Detecting Power Harmonics data of each distributed photovoltaic are sent to host computer, host computer can really realize
Monitoring on the polluter machine operation affecting the quality of power supply, can make power department provide for users
The electric energy of high-quality.
It is emphasized that embodiment described in the utility model is illustrative rather than determinate,
Therefore this utility model includes the embodiment being not limited to described in detailed description of the invention, every by this area skill
Other embodiments that art personnel draw according to the technical solution of the utility model, also belong to this utility model
The scope of protection.
