The integrated gasification combined cycle (IGCC) is a promising electrical generation system which combines a clean coal transformation technique with a high efficiency combined cycle system. Though this system is the focus of current energy source and power research, theoretical models for the system are still inadequate. Mathematical models of the system components were developed for the three pressure reheat steam water system in an air integrated IGCC system. Analysis of the off design performance for two kinds of operating modes provided insight to improve the efficiency of the air integrated IGCC system and the effect of the deaerator on the power output of the gas turbine and the system power supply efficiency. This work provides the theoretical basis for the development of a Chinese IGCC demonstration power plant.

The paper points out that fout main causes which damage computer network hardwares and operate faultly are lightning stroking,harmonics interference, earth potential fluctuating and distributed capacitor coupling between powerful current wires and mild current wires paralled.A common phenomenon but overlooked easily is a rush rising potential of earthing conductor and steel structure stroked by lightning counter-attacks through LV wires and power earthing neutral by means of rising referenced potential acting on board of electronic equipment. Analyses of harmonics considers not only three phase balanced load, but also unbalanced load, so it can sense comprehensively on element of positive sequence, negative sequence and zero sequence. The author also presents a IT system power supply adopting anti-lightning and anti-disturbance capacitive transformer, which can solve these problems. such as lightning, harmonics interference, earth potential fluctuating. and assure safety reliability of computer network and important electronic equipment.

指出造成计算机网络硬件损坏和运行不正常的主要因素,为雷击、谐波干扰、地电位扰动,以及强弱电线路并行导体之间分布电容耦合干扰等四个方面。雷击接闪时接地装置和钢筋电位骤升,引起参考地上高电位通过电子设备线路板,对低压电源线和电源接地中性点反击击穿,此现象常见而容易被忽视。对谐波的分析不仅要考虑三相对称的情况,还应考虑三相不对称的情况,修正以往对正序。负序、零序分量的片面认识。提出计算机网络采用防雷击、防干扰容性变压器隔离的IT系统供电方式,综合解决防雷击、防谐波干扰、防地电位扰动问题,确保计算机网络及重要电子装置的安全可靠性。
