Problems solved by technology

[0002] At present, in the construction of wind farms, there are communication barriers caused by data incompatibility between wind turbines and SCADA systems, which affects the equipment expansion and technical upgrading of wind farms
The international wind farm data communication standard IEC61400-25 has been released, and international mainstream wind turbine manufacturers are launching wind turbine controllers that comply with this standard, but there is a lack of corresponding communication protocol adaptation technology for wind farm equipment expansion and technology upgrades

Embodiment 1

[0019] Embodiment 1, by figure 1 , image 3 It can be seen that on the basis of retaining the power generation capacity of existing wind turbines, in the communication protocol adaptation project between non-standard wind turbines 8, IEC61400-25 standard wind turbines 9 and IEC61400-25 standardized SCADA system 10, the non-standard wind turbines The device-side gateway 11 is set up at the 8-end. The equipment-side gateway obtains the monitoring data of the original wind turbine by connecting the adapter 1. The configuration of the OPC client 2 by the configurator 6 realizes the connection with the communication interface of the original wind turbine.

[0020] The gateway internally uses the IEC61400-25 standard information model to reorganize the original wind turbine information, establishes a standard wind turbine information model, and saves it in the IEC61400-25 server 4 . The XML description file of the information model of the original wind turbine and the description...

Embodiment 2

[0024] Example 2 consists of figure 1 , figure 2 , Figure 4 It can be seen that when it is necessary to retain the original non-standard wind power generating set 8, and it is necessary to continue to use the original SCADA system 13 within a certain period of time, and at the same time introduce advanced wind power generating sets to carry out capacity expansion and communication protocol adaptation projects, the present invention The deployment is as follows: set up the device-side mode gateway 11 at the original wind turbine side, and install the application-side mode gateway 12 component at the SCADA master station side.

[0025] The operation mode of the equipment-side mode gateway 11 of the original non-standard wind power generating set 8-side is the same as that of Embodiment 1.

[0026] The application-side mode gateway 12 of the original SCADA system 13 provides standard upgrade services for the upper-level SCADA in the form of software components, and encapsulat...

Abstract

The invention relates to a gateway for monitoring the communication of a wind power station and a method for monitoring the communication protocol adaptation of the wind power station by applying the gateway. The problem of communication protocol adaptation between a wind generating set and an SCADA system (data acquiring and monitoring system) and the problem of international standardization for monitoring the communication of the wind power station are solved at the same time. The technical scheme is that: gateways consisting of IEC61400-25 servers, MMS protocol machines, connection adaptors and configurators are arranged at a wind power equipment end and an SCADA system end to establish a wind power station data communication network platform which is accordant with IEC61400-25 standard. Standard-based communication protocol adaptation between the wind power equipment and the system is realized on the platform, the problems of compatibility and standardization are solved and information sharing and interoperability between devices and uniform monitoring of the wind power station are realized.

Description

technical field [0001] The invention relates to a monitoring communication gateway in the field of electric power industry communication and an application method thereof in wind farm monitoring communication protocol adaptation. Background technique [0002] At present, in the construction of wind farms, there are communication barriers caused by data incompatibility between wind turbines and SCADA systems, which affects the expansion of wind farm equipment and technology upgrades. The international wind farm data communication standard IEC61400-25 has been released. International mainstream wind turbine manufacturers are launching wind turbine controllers that meet this standard. However, there is a lack of corresponding communication protocol adaptation technology for wind farm equipment expansion and technology upgrades. There is an engineering need to address the above issues. Contents of the invention [0003] The purpose of the present invention is to provide a met...
