Embodiment Construction

[0045] The present invention adopts the general rules defined by the IEC60870-5 series of protocols, including protocol structure, link layer (transmission rules, transmission frame format), application layer (application information element, application service data unit), user process (basic application function) .

[0046] The method adopts the unbalanced transmission rule in the specific implementation, takes the wind farm as the controlled station / slave station, and the power grid dispatching center as the control station / starting station.

[0047] When the initialization of the initiator station and the slave station is successful and the link layer is available, all the following application functions should be available and can run simultaneously:

[0048] Station (total) call (query)

[0049] The station summon command requests the controlled station to transmit to the controlling station the actual status of information that is usually transmitted in bursts. The st...

Abstract

The invention discloses a transmission method used for transmitting wind power information between a power grid dispatching center and a wind power electric field, aiming at realizing the mixed transmission of real-time data and historical data required by dispatching wind power and the transmission of the information of a numerical weather forecast file, a wind power forecast result, an automatic generation control (AGC) / automatic voltage control (AVC) regulating command, and the like. The communication method is formulated on the basis of taking IEC60870-5 serial protocols as a reference by giving the consideration to the requirement on remote maintenance configuration of wind power field terminal equipment. The communication method maintains the maximum compatibility with the standard defined by the IEC60870-5 and is correspondingly expanded and supplemented according to actual requirements, thus the protocol conforms to the standard to the greatest extent, is easy to realize and reduces the cost.

Description

technical field [0001] The invention relates to the field of electric power system automation control, in particular to a transmission method for transmitting wind power information between a grid dispatching center and a wind farm. Background technique [0002] In recent years, with the large-scale development of wind power generation, the proportion of wind power in the power supply has increased significantly, and the optimal dispatch of wind power based on wind power prediction is an important technical support means for large-scale integration of wind power into the grid. In order to realize the optimal scheduling of wind power, the characteristics and special needs of wind power generation must be considered, which are mainly reflected in: [0003] Due to the strong randomness of wind speed and the characteristics of fast data changes, in order to provide accurate and timely wind turbine basic data for wind power forecasting, the terminal equipment on the wind farm sid...
