Equipment；
3) conversion equipment carries out real time parsing and conversion to receiving data, is converted to suitable RS-485 transport-type；
4) RS-485 modules are utilized by the data broadcasting after conversion to each target terminal.
The step 1) is specifically defined as follows：
SLRP is active output, and SLRQ is idle output,Exported for power factor, wherein SLRP, SLRQ,Common data class is ASG, and ZLSR includes data set dsSolarParameter, data set dsSolarParameter
Report-control block be brcbSolarParameter.
After the exchange device receives multicast message, judge that the data set reference in GOOSE message, GOOSE identify, it is inconsistent
Then abandon；It is consistent then carry out packet parsing, the remote regulating data value in GOOSE message is obtained, by accessing shared real-time database logarithm
Judged according to uniformity, the remote regulating data in GOOSE message are with specific type of message, the priority level of message, using disappearing
Cease shared mechanism to send, be transmitted to each RS-485 modules and be transmitted.
The RS-485 modules first carry out coefficient adjustment, skew adjustment, data type conversion to the data received, with fixed
Free burial ground for the destitute location is that 0xFF specific remote regulating data packet format is broadcasted to every inverter, and every inverter is according to issuing in packet
Data carry out that photovoltaic is active or the regulation of reactive power, so as to realize active or reactive power the regulation of whole photovoltaic plant.
The beneficial effects of the invention are as follows：The present invention utilizes GOOSE based on the GOOSE services in IEC61850 standards
One-to-many transmission mechanism, is extended to GOOSE service models, defines the entitled ZLSR of LN, crucial to ZLSR related DO
Parameter is defined, and is carried out multicast to the control data of photovoltaic generation using GOOSE transmission mechanisms, is transferred to each conversion and sets
It is standby, the data received are parsed and changed by conversion equipment, every inverter is broadcast to finally by RS-485.Every
Inverter carries out that photovoltaic is active or the regulation of reactive power according to the data that issue in packet, so as to realize whole photovoltaic plant
Active or reactive power regulation.The GOOSE models in the existing standards of IEC 61850 are extended, utilize GOOSE multicasts and RS-
485 broadcast cooperated, adjust whole photovoltaic plant it is active with it is idle, significantly improve power adjusting response speed,
Reduce the fluctuation of power network, there is high engineering practical value.
