在现代电力系统中STATCOM(静止同步补偿器)能对电力系统的无功潮流进行快速灵活的调整,从而达到提高电力系统综合稳定性的目的。文章在Matlab中搭建了基于阶梯波调制法的STATCOM的仿真模型并进行了仿真分析,阶梯波调制法是利用阶梯波逼近正弦波的原理,通过控制各个晶闸管的通断来产生相应的阶梯波,将各个H桥的阶梯波进行叠加来逼近正弦波的。  相似文献

The objective of this paper is to carry out a counterfactual analysis of the impact of alternative exchange rate regimes on the volatility of the nominal effective exchange rate (NEER) and the bilateral rate against the US dollar for nine East Asian countries after the Asian financial crisis. Our hypothetical regimes include a unilateral basket peg (UBP), a common basket peg (CBP) and a hard peg against the dollar. We find that a UBP would minimise effective exchange rate volatility for all countries and provides the highest regime gains compared to actual. Although the gains for a CBP are always less than those for a UBP, the absolute differences between the two regimes appear to be small. In terms of the bilateral relationship against the dollar, the gains from a UBP or CBP could be quite significant for the non‐dollar peggers since a fall in effective instability would be accompanied by a fall in bilateral instability.  相似文献

Early in the gestation stage of the new labor contract law, the intensive debates sparked by worries and doubts prevailed, and the event of Huawei Group forcing their employees to re-apply for their jobs made this controversy reach fever pitch. When it came into effect on 1st January, 2008, confusions still bothered people of all sides: someone were on thorns about the increased cost and found wry ways to digest it, and someone were scramble to their rights and looked for shortcut to get it, etc. in particular, textile industry featuring labor-intensive will increase 20% on average in terms of cost, so how to cushion the blow and reverse adversity become prominent, what’s more, we should emancipate our mind to create profits rather than make ourselves balky with losses. Brand-building, technology application as well as expanding business abroad where with relatively cheap cost, etc, all of which can be utilized. In fact, launch of new labor contract law coupled with other polices home and aboard and materials cost increment lift the threshold of Chinese textile industry and rendered a new shuffling, so that the conception of "survival of the fittest" becomes the last straw we should grasp……  相似文献

A Bayesian hierarchical mixed model is developed for multiple comparisons under a simple order restriction. The model facilitates inferences on the successive differences of the population means, for which we choose independent prior distributions that are mixtures of an exponential distribution and a discrete distribution with its entire mass at zero. We employ Markov Chain Monte Carlo (MCMC) techniques to obtain parameter estimates and estimates of the posterior probabilities that any two of the means are equal. The latter estimates allow one both to determine if any two means are significantly different and to test the homogeneity of all of the means. We investigate the performance of the model-based inferences with simulated data sets, focusing on parameter estimation and successive-mean comparisons using posterior probabilities. We then illustrate the utility of the model in an application based on data from a study designed to reduce lead blood concentrations in children with elevated levels. Our results show that the proposed hierarchical model can effectively unify parameter estimation, tests of hypotheses and multiple comparisons in one setting.  相似文献
