Problems solved by technology

At present, the node status identification of distribution automation is basically completed by the master station. However, the real-time transmission of status information by the master station is poor, generally at the second or minute level, which cannot meet the real-time load transfer requirements.

Embodiment Construction

[0021] In order to better understand the substances of the present invention, the present invention is further elaborated in conjunction with specific embodiments and drawings.

[0022] The present invention provides a real-time transmission method of distribution network nodes, as an example of a DC distribution network, such as figure 1 and figure 2 As shown, including the following steps:

[0023] Step 1: Define the positive direction of each contact switch of the system, confirm the upstream nodes, downstream nodes, and T nodes of each contact switch.

[0024] In the unit of contact switch, the upstream node and the downstream node are determined along the system positive direction, and when the plurality of contact switches have the same upstream node, they are T nodes. Such as image 3 As shown, in the region one, S1 is the S2 upstream node, S2 is the downstream node of the S1; in the region II, S3 is the upstream node of S4 and S5, so S4 and S5 are T nodes; S6 is S4 and S5 d...

Abstract

The invention discloses a real-time transfer method of distribution network node status, which belongs to the technical field of distribution automation, and comprises the following steps: configuring GOOSE communication parameters for contact switch nodes that need to transfer status information; dividing the status information into unconditional transfer information and conditional transmission of information; the distribution automation terminal distributes the distinguished status information. The invention provides a real-time transfer method for node states of a distribution network, which can realize fast and reliable transfer of node states.

Description

Technical field [0001] The present invention relates to a real-time transmission method of distribution network nodes, belonging to the field of power distribution automation. Background technique [0002] In order to improve the power supply capacity and reliability of the distribution network, the network topology of the distribution network is developed from the single power supply radiograph to the multi-power ring network. In addition, with the rapid development of distribution network automation and the construction of DC distribution network, the construction of DC mixed distribution networks, network operation is more flexible, and the distribution network is more flexible, and the distribution network wants to achieve fast load, such as connecting power, Node status of upstream fault isolation signals needs to be quickly identified. The current distribution automation node status recognition is basically completed by the master, but the main station is poorly time-sensit...
