This article intends to reveal the importance of protecting the ecological environment for human health from the close relationship between the environment and human health, and the deterioration of the ecological environment that caused various pollution and disasters has created serious harm to human health. At the same time, it analyzes the major problems between contemporary environmental security and human health, and proposes effective measures to address environmental security and human health in response to these problems, and calls on all countries in the world to work together to build a community of human ecological fate to ensure ecological security and human health, which is going to expand a broader living space for mankind and create better conditions for development. The current sudden and rapid rampage of the new coronary pneumonia epidemic in the world poses a serious threat to human survival and development, it also fully demonstrates the great value of the integration of ecological environment security and people's health simultaneously. Human production and life activities have a profound impact on the environment, at the same time, the environment also affects human health. There is a dialectical relationship of interaction, mutual influence and mutual promotion between ecological security and people's health. Therefore, countries in the contemporary world must strengthen cooperation to maintain the safety of the ecological environment and protect human health. 1 The main harm to human health caused by the deterioration of contemporary ecological environment At present, due to the weak awareness of human ecological environment protection, it has caused air, water, noise and other pollution, which have seriously affected human health. The deterioration of the ecological environment is threatening the current survival and development of human beings.","PeriodicalId":11369,"journal":{"name":"DEStech Transactions on Environment, Energy and Earth Science","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90193439","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A new method is presented to solve the error of energy meter by iteration. Firstly, the daily electricity data is collected and sifted through to classify the data for light-load and no-load meters. Then, by applying the outlier line-loss rate treatment method, it can obtain the invariable-loss & line-loss rate & the suspected out-of-tolerance meter and their initial values. After that, the meter error, invariable-loss, and line-loss rate can be calculated by the improved meter error estimation model. Based on the computed results, the data with relatively high and low line-loss rate are removed. It is to guarantee that the line-loss rate of data is within a small range. The sifted process removes the outliers and avoids the mis-deletion of the valid data, which improves the calculation accuracy. The proposed method proves to be effective in out-of-tolerance meter search by verifying the data from two different scale distribute-electricity transformer districts (DETDs) and comparing with the traditional least-squares method (LSM). The algorithm is easily applicable to small computation burdens.","PeriodicalId":11369,"journal":{"name":"DEStech Transactions on Environment, Energy and Earth Science","volume":"74 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89823327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
