| Abstract: | This paper is concerned with the least-square method based on a parameter estimation model and a temperature forecasting method. The measurable temperature parameters of various stations are calculated and forecasted by a higher management computer, realizing alarm-giving for power cable joint fault in advance. In addition, the structure, principle and role of the system, the single-chip subsystem and the effect of tests are described on spot. The method proposed requires not only less alarm time than the conventional practice using the unity parameter limit position value but also greatly improving the accuracy of fault forecasting. |
