In digital relay, the percentage of noise will increase rapidly with the increase of sampling rate when derivation calculus is substituted by sampled difference term. to solve this problem, a new method using fragment function integrated with the least square algorithm is proposed in this paper. the influence of white noise is greatly reduced and the accuracy of the dead angle calculation is nicely improved after adopting the new method
在數字式保護中，如果用差分代替求導將導致噪聲的百分比誤差隨著采樣頻率的提高而劇增，本文對此進行了分析並提出了用分段樣條函數最小二乘法來計算電流波形的導數值，以便在提高采樣率的同時降低噪聲誤差的影響，並將其應用於基於32位浮點dsp的新型變壓器保護裝置。 -
It is designed for a power plant in order to reduce the workload of the relay protection workers, decrease the percentage of protection device ' s false action, and increase the work efficiency of the device in power plants
可視化的發電廠保護整定綜合系統是為減輕發電廠繼電保護工作人員的勞動強度，降低保護設備的不正確動作率，提高發電廠設備的運行效率而開發。 -
Firstly, the paper introduced the commonly hardware configure of microcomputer relaying and the function of every module of industry controlling computer std90386. secondly, the paper introduced several types busbarprotection which was commonly installed on electric power system and the characteristic of mv or lv system with low current grounding. based on it, the paper put forwards the theory of percentage - restraint differential relay. after that, in the discussing every problems of the relaying working the paper put the emphasis on the negative effect of the ct saturation and countermeasure
本文首先介紹了微機保護裝置的一般硬體配置以及作為裝置硬體平臺的std90386工控機各組件模板的功能，然後分析了目前電網系統裝設的母線保護的各種類型以及中、低壓小電流接地電網的特點，在此基礎上分析、介紹了作為本保護動作原理的「比率制動式差動保護」原理。
