Embodiment Construction

[0054] The specific embodiment of the present invention is as follows figure 1 shown.

[0055] A distribution transformer gear identification algorithm in this embodiment is as follows:

[0056] 1. Establish the topology relationship of distribution transformers:

[0057] The establishment of the topology relationship of distribution transformers mainly solves the parent-child relationship of distribution transformers. The distribution network is usually closed-loop design and open-loop operation, and a short-term ring network will appear when the load is reversed or a fault occurs. The distribution transformer group structure and tree of this operation mode are The structure is similar. In order to find the adjacent distribution transformer of the distribution transformer whose gear is to be determined, that is, the distribution transformer of the parent node, a three-pronged linked list can be considered as the chain storage structure of the distribution transformer group. ...

Abstract

A distribution transformer gear recognition algorithm, the algorithm uses the distribution transformer topological relationship connected to the same 10kV line to determine the predecessor and successor relationship between adjacent distribution transformers; analyze the different gear voltages of adjacent distribution transformers Difference, if the voltage drop generated by the line impedance is regarded as noise, the voltage of the adjacent station area is not in the same gear, which will cause a different voltage difference, and then determine the gear relationship of the adjacent distribution transformer; through the adjacent station area Comparing the voltages of the two stations, and completing the analysis of the voltage levels of all stations. The algorithm of the present invention does not require the operation and maintenance personnel of the station area to check the actual gear position of the distribution transformer, but uses the existing operating data of the distribution transformer to realize online calculation of the gear position of the distribution transformer, thereby providing the power supply reliability of the station area. The algorithm of the invention can accurately determine the actual gear position of the distribution transformer, and is suitable for large-scale application and popularization.

Description

technical field [0001] The invention relates to a gear position identification algorithm of a distribution transformer, and belongs to the technical field of power distribution. Background technique [0002] The qualified rate of voltage in Taiwan area is one of the main standards for measuring power quality. According to the relevant regulations of the "Technical Guidelines for Distribution Networks", the voltage deviation of 220V single-phase power supply is +7% and -10% of the nominal voltage. With the increase of rural-related industrial industries and the development of mechanization of secondary industries, the rural load generally has the characteristics of obvious seasonality, strong time period and large fluctuation. Distribution transformers are usually light-loaded with high voltage, while summer and winter, spring irrigation and autumn harvest, The sudden increase in seasonal load during the New Year, festivals, roasted tea and cigarette making, etc. causes the v...
