Embodiment Construction

[0025] Below in conjunction with specific embodiment and description Figure 1-4 The present invention is further described in detail.

[0026] The invention uses the real-time simulation technology of the power system to simulate the electromagnetic transient process of various faults, close-loop checks the action logic of the protection device, and investigates the interoperability performance between the secondary devices and the performance of the communication network.

[0027] In addition, using power line communication technology, the station power line in the substation is used as a natural channel for long-distance transmission of test data, and there is no need to lay a large number of long test optical fibers at the substation infrastructure and maintenance sites. The equipment wiring is simple, flexible, and highly portable, which is convenient for engineering implementation .

[0028] See attached Figure 1-4 ,Such as figure 1 As shown, this embodiment includes...

Abstract

The invention discloses an intelligent transformer substation secondary equipment integrated test system based on power line communication. The system comprises an intelligent transformer substation real-time simulator, a first power line communication interface device, a station electricity line channel and distributed data terminals. The intelligent transformer substation real-time simulator is connected with the first power line communication interface device via a high-speed bus. The distributed data terminals are arranged beside spacing control cubicles and are corresponding to the spacing control cubicles in a one-to-one way, and merging units and intelligent terminals are respectively connected with the corresponding distributed data terminals via optical fibers. The spacing control cubicles are arranged beside onsite primary equipment. The distributed data terminals communicate with the first power line communication interface device via the station electricity line channel. The intelligent transformer substation secondary equipment integrated test system based on power line communication has characteristics of being portable and modularized so that single function testing can be performed on partial equipment, and simulation testing of complex fault and developing fault with cooperative matching of protection can also be performed.

Description

technical field [0001] The invention relates to the field of secondary equipment testing of substations, in particular to an integrated testing system for secondary equipment of intelligent substations based on power line communication. Background technique [0002] In recent years, the construction of my country's smart grid has risen to the level of national strategy, and smart substation is one of the core platforms for energy conversion and control in the construction of a strong smart grid, and its planning and construction have been fully rolled out. Based on the IEC61850 standard, the smart substation widely adopts advanced technologies such as digital sampling, smart primary equipment and fiber optic Ethernet, which greatly improves the reliability and intelligence level of the substation, and also puts forward new requirements for the commissioning and testing of the substation. At present, the existing test tools for the secondary equipment of the intelligent stati...
