Based on the acquired data and operating experiences from pilot experiments , the demonstration project is devised comprehensively , which is concerned with so many aspects , such as choosing the site of demo plant , the portions " arrangement , gasification subsystem , condensation subsystem , tar catalytic reforming subsystem , purification and dryness subsystem , gas pipe networks and fire control subsystem . furthermore , economic assessment has been given preliminarily 在中试试验所获得试验数据和运行经验的基础上，进行了120户规模的集中供气示范工程的设计，包括气化站选址及站内布置、气化系统设计、冷凝系统设计、焦油催化裂解系统设计、净化干燥系统设计、输气管网设计、消防安全设计等，并进一步对项目的技术经济性进行了简单评估，为示范工程的建设和调试运行提供了技术保障。
These character based on sichuan power network ' s practice operation experience , in allusion to the config of the carrier wave protection in bypass breaker operating , through the study of protection ' s typical config : one side lfp - 902a , one side csl - 101a , proceeded comprehensive act module test , noted plenty of first hand test data and wave picture , proceeded detailed theory analyses , plenitude demonstration atresic type carrier wave distance protection when twain side atresic type logic is not completely same , basically can fill power network ' s requirement to relay of reliability selectivity speedly and sensitively 本文结合四川电网的实际运行经验，针对旁路开关代路运行时的保护配置情况，通过对旁路代路时保护典型配对组合：一侧lfp - 902a ，一侧csl - 101a的保护配置情况的深入研究，做了全面的动模试验，记录了大量的第一手试验数据和波形，进行了详细的原理分析，充分验证了高频闭锁式距离零序保护在两侧闭锁式逻辑不尽一致的情况下，基本能够满足电网对继电保护的可靠性、选择性、快速性以及灵敏性的要求。
The inner - plant economical operation of lijiaxia hydropower station is studied based on the disadvantageous operating mode area of the units determined by school of civil engineering of tianjin university and the actual operating experience of the lijiaxia hydropower station in the last a few years 摘要以天津大学建筑工程学院确定的李家峡水电站机组的不利工况区为依据，以近几年来该水电站的实际运行经验为参考，在综合考虑机组初始运行状态、机组振动特性、机组出力、下泄流量、水库蓄水量和电网负荷平衡等因素的基础上对李家峡水电站的厂内经济运行进行了研究。
Aiming at the practice of nanjiang power station of tian jin port , combining with the concrete work content of myself , absorbing the building and running experience of the electric power system of nanjiang , according to the related standards of the national electric power system , the general design of the nanjiang electric power system of tian jin port is carried out . because this project is very large , the first system , the second system and three remote control system of the nanjiang 35kv power station are calculated , demonstrated and analyzed in detail in this article . the supply electricity feature of the port district is combined closely with the whole design course 本文针对天津港南疆建设的实际，结合自己的具体工作内容，在汲取天津港北疆电力系统建设、运行经验的同时，依据国家电力系统有关规范，对天津港南疆电力系统进行总体设计，由于此项工程浩大，本文重点对南疆35kv电站的一次系统、二次系统、三遥系统，作了较详细的计算、论证和分析说明，整个过程紧紧结合港区供电的特点，大胆引用国内领先的技术和设备。
