In order to work out the accident caused by the impact or frequent current into the ground on person or equipment near the substation when transmission line tower is short-circuited, the technology of multi-point monitoring to scattered current in the ground were studied in this paper. And then the method is verified by simulation and experiment. At the same time, the scattered current of not monitored...
The current reckoning method is based on the system operation network and modeling to achieve current reckoning network model, using the link reckoning technique and branch current measurement to identification and calculation. Analysis current difference identification features, to identify bad data, then correct the bad data, on the basis of the revised branch current to determine the state changes...
This paper describes the design of a kind of 1553B bus test unit based on multi-core DSP and FPGA. It is used to realize the 1553B bus protocol test and electrical performance test. This paper mainly describes the design of the 1553B bus protocol analysis module for protocol test, the design of the high-speed ADC module for signal acquisition, the design of the high-speed DAC for signal generation...
Lightning is an important factor in the biosafety of the surrounding area of the tower, and its core lies in the dispersed current damage. Lightning current flows into the earth, resulting in the imbalance of current, the unbalance of current leads to the unbalance of the voltage around the tower. Aiming at the problem of lack of soil dispersed current test and safety assessment, the experiment of...
