Problems solved by technology

[0002] At present, the remote measurement of the operation of the distribution network is blank. The existing comprehensive tester for distribution operation can only realize automatic data collection, and manual on-site meter reading is required to extract the data, and then input the data into the main computer for recording and analysis. The workload is heavy. The data discrepancy caused by the large recording time difference seriously affects the accuracy of data statistical analysis and hinders the process of automatic management of power distribution system
At the same time, due to the large quantity and wide area of ​​distribution transformers, the laying of lines and installation conditions are very complicated, and the operation conditions are also ever-changing. Often, low voltages cause serious load imbalances, overloaded transformers are burned, and power factor and voltage pass rates are low, which seriously affects distribution. The safety and economy of the normal operation of power facilities, especially the manual on-site meter reading and wired data transmission, are far from meeting the actual needs of the current distribution network operation.

Embodiment

[0014] Example: 10KV distribution transformers are selected for effective online monitoring, remote communication and offline analysis. For the on-site monitoring part, 51 series single-chip microcomputers are used as the core to develop monitoring devices, and 12-bit A / D sampling components are selected to ensure accuracy; all components And the whole machine has been strictly inspected to ensure the quality. In this example, the GSM wireless communication network of China Unicom is selected as its transmission subsystem to ensure the smooth flow of the communication channel. A wireless modem produced by MOTOROLA is used as the communication device. The computer software of the master station is developed under WINDOWS98 using WISUAL FOXPRO to realize remote meter reading, real-time query functions, and process historical data for management personnel to analyze.

[0015] The invention solves the long-standing problems of difficult meter reading, heavy workload, and large co...

Description

technical field [0001] The present invention relates to an automatic monitoring system for power supply, more specifically about a distribution transformer, which integrates the functions of on-site automatic monitoring, recording and analysis, and remote data acquisition into one transformer for on-line monitoring, remote communication and off-line analysis of power distribution load monitoring system. Background technique [0002] At present, the remote measurement of the operation of the distribution network is blank. The existing comprehensive tester for distribution operation can only realize automatic data collection, and manual on-site meter reading is required to extract the data, and then input the data into the main computer for recording and analysis. The workload is heavy. The data discrepancy caused by the large recording time difference seriously affects the accuracy of data statistical analysis and hinders the process of automatic management of power distribut...
