Embodiment Construction
[0045] Such as figure 1 As shown, the steps of the hybrid communication method between the substation communication gateway machine and the dispatching master station system in this embodiment include:
[0046] 1) Configure the clipping rules of each dispatching master station on the substation communication gateway in advance according to the requirements of different dispatching master stations, and the tailoring rules define the voltage level and data category of the information required by the dispatching master station;
[0047] 2) When the dispatching master station system of the target dispatching master station needs to communicate with the substation monitoring system of the substation, jump to step 3);
[0048] 3) The substation communication gateway machine reads the clipping rules corresponding to the target dispatching master station, and according to the clipping rules, cuts and merges the original data of the substation to obtain the data required by the target ...

The invention discloses a hybrid communication method for a communication gateway machine of a transformer substation and a main dispatching station system. The hybrid communication method comprises the following steps that: a clipping rule of each main dispatching station is pre-configured on the communication gateway machine of the transformer substation; when a target main dispatching station needs to communicate with a monitoring system of the transformer substation, the communication gateway machine of the transformer substation reads the clipping rule and clips and combines original data of the transformer substation so as to obtain data required by the target main dispatching station; a communication mode is selected according to real-time requirements of a system application of the target main dispatching station; and the data required by the target main dispatching station obtained by combination is sent to the target main dispatching station from the communication gateway machine of the transformer substation. According to the invention, information clipping and combining can be automatically completed; errors possibly due to artificial configuration can be eliminated; communication mode selection by users can be shielded through seamless switching having configurable contents; furthermore, user data transmission requirements having different real-time performances can be satisfied at the bottom layer; communication modes and contents are flexible; hardware is unnecessary to increase; and the hybrid communication method is good in compatibility and wide in application range.
Description
technical field [0001] The present invention relates to electric power automation technology, in particular to a hybrid communication method between a substation communication gateway and a dispatching master station system, which is used to respond in different communication ways according to the different requirements of each dispatcher, and to provide different dispatching master station systems Response speed, content, and quality data meet the data requirements of different dispatching master station system applications. Background technique [0002] At present, data transmission between the substation communication gateway and different levels of dispatching (regulation) center systems is traditionally carried out through the establishment of data links. The transmitted content is the primary equipment information of the power grid collected by the substation and the secondary equipment inside the substation. Device information is generally transmitted in a different c...
