介绍法国电网的电能质量承诺,包括输电运营商(TSO)的质量承诺和配电运营商(DSO)的质量承诺.TSO和DSO在作出电能质量承诺的同时,还利用入网规则以协议的方式来考虑和限制每个客户的负荷和分布式电源时电能质量的影响.这些协议的实施表明,只有遵守承诺,加上电网运营商与用户双方共同作出努力,才能获得全面良好的电能质量,对于电网干扰评估,建议使用基波潮流计算与多相谐波注入相结合的方法.这个方法利用很短的计算时间就能对非线性负荷建模情形给出可接受的结果.所提议的频域方法的要点在于,将每个谐波源逐一地同时作为扰动源和受扰者来考察,以便计及扰动源之间的相互作用.研发了一个即插即用的HVDC组件并将其用在文章最后部分实例研究中.
介紹法國電網的電能質量承諾,包括輸電運營商(TSO)的質量承諾和配電運營商(DSO)的質量承諾.TSO和DSO在作齣電能質量承諾的同時,還利用入網規則以協議的方式來攷慮和限製每箇客戶的負荷和分佈式電源時電能質量的影響.這些協議的實施錶明,隻有遵守承諾,加上電網運營商與用戶雙方共同作齣努力,纔能穫得全麵良好的電能質量,對于電網榦擾評估,建議使用基波潮流計算與多相諧波註入相結閤的方法.這箇方法利用很短的計算時間就能對非線性負荷建模情形給齣可接受的結果.所提議的頻域方法的要點在于,將每箇諧波源逐一地同時作為擾動源和受擾者來攷察,以便計及擾動源之間的相互作用.研髮瞭一箇即插即用的HVDC組件併將其用在文章最後部分實例研究中.

Grid Power Quailty Commitments in France are introduced,including the Power Quality Commitments of Transmission System Operator(TSO)and the Power Quality Commitments of Distribution System Operator(DSO).Undertaking the commitments,TSO and DSO are using connection rules to take into account and minimize the impact on power quality of each customer(load or distributed generation)in the way of contracts.The practice of these contracts shows that a good overall power quality can only be achieved by respecting commitments and doing effort from both of grid and customer sides.For grid disturbance assessment,it is suggested to use multi-phase harmonic injection method with fundamental power flow.This method can give an acceptable result with very short computing time for non-linear load modelling.The key point of proposed frequency domain method is that each harmonic source is individually considered as both disturbance source and disturbance receiver in order to take into account interactions between sources.A plug & play HVDC component has been developed and used in one of two case-studies in the end of this article.
