Embodiment

[0033] A cooperative control method of a distributed FA and a master station FA with adaptive communication time delay, comprising the following steps:

[0034] Step 1. Establish an interaction model between intelligent distributed FA and master station FA considering communication delay;

[0035] Described step one comprises the following steps:

[0036] 1.1 A communication delay description model is added to the logical node for data interaction between the distributed FA and the centralized FA of the main station, which is used to describe the timeliness of the logical node data;

[0037] 1.2 Various fault type models interacting in the intelligent distributed FA and the master station FA add a communication delay model to express the timeliness of various fault types.

[0038] Wherein, the communication delay models added in the logical node model and the fault type model are all modeled based on the IEC61850 standard.

[0039] Object-oriented modeling technology is adop...

Abstract

The invention discloses a distributed FA and master station FA cooperative control method for an adaptive communication time delay. The method comprises the following steps that an intelligent distributed FA and master station FA interaction model considering the communication time delay is established; the distributed FA considering the communication time delay and the master station FA are cooperatively controlled; and when the communication time delay is unstable, the distributed FA and master station FA cooperative control strategy is adaptively adjusted. The method is reasonable in design, the distributed FA can adapt to various communication modes such as an optical fiber, a wireless private network and a wireless public network, the cooperative control strategy of the distributed FAand the main station FA adapts to the communication time delay, the line fault processing is more reliable, the fault isolation range is more accurate, and the power supply reliability is improved.

Description

technical field [0001] The invention belongs to the technical field of power distribution automation, and in particular relates to a cooperative control method of a distributed FA and a main station FA with adaptive communication time delay. Background technique [0002] Realizing distribution automation is the requirement of power system development, and feeder automation (FA) technology is the core technology of distribution network automation. Feeder automation is mainly implemented in two ways: local distributed FA and centralized FA. The power distribution backbone loop mainly adopts the centralized FA control method, which is controlled through the coordination of the master station system and with the help of communication information; the branch line and radiation power supply mostly adopt the local distributed FA control method, and fast control is realized in a local area. In recent years, with the improvement of the degree of automation, the control mode of centr...
