study and Mitigation of subsynchronous Oscillations with ssC Based sssC

引用

Journal of power and Energy Engineering 2015年第9期3卷 33-43页

作者： Mohan p. Thakre Vijay s. Kale Koteswara Raju Dhenuvakonda Bhimrao s. Umre Anjali s. Junghare Department of Electrical Engineering Visvesvaraya National Institute of Technology Nagpur India

This paper proposes a powerful subsynchronous component based (ssC) controller to mitigate the subsynchronous resonance (ssR) with statics synchronous series compensator (sssC). The mitigation of ssR is achieved by increasing the network damping at those frequencies which are close to the torsional frequency of the turbine-generator shaft. The increase of network damping is done by the extraction of subsynchronous component of voltage and current from the measured signal of the system. From the knowledge of subsynchronous components, a series voltage is injected by sssC into the transmission line to make the subsynchronous current to zero which is the main cause of turbine oscillations. To analyze the effectiveness of the proposed control scheme, IEEE first benchmark model has taken. The results show the accuracy of the proposed control scheme to mitigate the Torque amplification of ssR.

The Gentio metagranitoid presents equigranular and porphyritic facies, modal composition ranging from tonalite to monzogranite with calculated T_(Zr)st samples. Its mineralogy is dominated by quartz and feldspar(77% to 95%), biotite is the only mafic mineral present(2% to 18%) and, titanite, zircon, apatite, allanite are important accessory phases. These rocks range from metaluminous to weakly peraluminous, and have large variation in major and trace elements, and high alkali contents(>6 wt.%). Zircon analyses by LA-ICp-Ms and sHRIMp yielded a concordia age of 2 119±10 Ma for the porphyritic facies and an upper intercept age of 2 111±15 Ma for the equigranular facies. The whole-rock sm-Nd T_(DM) ages vary from 2.4 to 2.8 Ga with ε_(Nd)(2.1) values between -0.7 and-5.3, indicating crustal derivation from distinct and/or heterogeneous protoliths. Field observations indicate that the Gentio metagranitoid was formed through different pulses of magma. Individual batches were subject to little or even no fractionation process after its emplacement. Although the Gentio metagranitoid crosscuts metamafic and metaultramafic rocks akin to an oceanic arc setting, this pluton is likely originated by partial melting of a more evolved quartz-feldspathic crustal igneous rock in a post-collisional environment, after the accretion of the arcs from the Mineiro belt and rocks of the Mantiqueira Complex.

辽宁海城小孤山史前遗址的旧石器时代晚期文化层中出土了兽牙穿孔垂饰与骨制小圆盘，其年代约为距今3万年前。这批装饰品与骨制标枪、骨针等人工制品、勒瓦娄哇石核等石器工业，反映了该地区由旧石器时代中期向晚期过渡的历史过程。小孤山遗址出土装饰品在风格特征与工艺技术上与欧亚地区及中国北方的旧石器时代晚期早段装饰品存在明显的相似性。小孤山遗址在时间与空间上确立了现代行为类型在旧石器时代中期向晚期过渡时期的边界，是旧石器时代晚期文化传统由西伯利亚起源中心向周边扩散最重要的代表性遗址之一。小孤山遗址装饰品极大地填补了中国境内史前装饰艺术研究的空白，同时反映了欧亚地区东部早期象征主义活动发展的整体趋势和区域特征。

A convenient synthesis of quino[2,3-b] [ 1,5]benzoxazepines from substituted 2-chloroquinoline-3-carbaldehyde and 2-hydroxy- aniline by using stable, non-toxic and inexpensive catalyst 1,8-diazabicyclo-undecan-7-ene （DBU）/silica gel is described. This method affords the quino[2,3-b][1,5]benzoxazepines under the influence of microwave irradiation （360 W） in solvent-free conditions within short reaction times （2-3 min）, giving high yields of products （93-96%）.
