The fundamental principle and function of state estimation in district power system is described. It uses the redundancy of real time measurement system to improve data accuracy,then to reject error information and estimate system states.
with the high integration and performance. The system can provide one kind of technology support in real production decision based on the scientific line loss calculation, comparison and analyse under a new kind of line loss management mode. The system is a scientific line loss management software platform, which can improve the data correctness and working efficiency.
Secondly, CORBA's performance is optimized by means of batch sending data, package splitting, improving data granularity. what's more,the performance is tested. By combination the optimized CORBA into Multi-Agent, We have designed the distributed computational model based on Multi-Agent, and also constructed the whole architecture of AOSDE.
This work proposed an intelligent harmonic measurement method based on 80C196KC chip, which realized the frequency trace with the aid of 80C196 chip's high-speed importation and the software timer. The application of this method overcomes the influence of frequency variety on measurement and, also improves the speed of data sampling.
It mainly introduces Jinzhong electric power supply branch company making use of optical fiber channel to realize interconnection between the lines of company branches,aiming to raise the real-time character,dependability,continuity of data gathering,so as to realize the resources sharing ability and some prospects of its applications.
Additional topographic surveying or SAR interferometry should be used to improve the data quality in that area.
Signal-to-noise ratios and coefficients of variation are significantly improved by increasing Cy3 to 150-180 pmol, but any further increase does not improve the data.
Instead of working directly with screws, the optimisation of the procedures was carried out with metallic plates homogeneously coated to improve the data comparability.
Efforts to collect more or better data to improve the data quality of those stored in a GIS would not reduce uncertainty in the decision significantly.
In this paper, we propose two updated data dissemination methods to not only reduce the number of accesses to old replicas, but also to improve the data accessibility in ad hoc networks where data items are updated regularly.
In this paper, several problems in data acquisition program are discussed in detail, which include improving the speed of data acquisition,designing the data buffer, selecting a scheme of soft filter, and calculating the time interval precisely.How to resolve these four problems is an important subject in the study of data acquisition program for computer aid test of hydraulic turbines.
The way of real time sampling and disposition in structure of sampling channels have to be determined first when the computer protection system is developed.Detailed analysis is given here and a few valid measures to increase the transfer rate of data are introduced.
This paper analyzes the problem of raising the frequency rate of an A/D converter as discussed in documents 3 & 4.A solution is to use multiple A/D converter in parallel. Thus,the data sampling frequency is raised.The A/D converter function chart and parallel converter circuit is given.This method has been tested and proven to be effective.
