Abstract:
为提高电网调度运行的精益化管理水平,美国PJM电力市场于2007年提出了理想调度评估方法。与传统的电网运行评估方法相比,理想调度从后评估的角度,通过“反演”计算电网调度运行中的最理想方案,以量化评估实际运行情况与理想方案之间的差距。本文将理想调度与实际的业务过程相结合,全面辨识影响电网运行效益调度程度的各类因素。通过引入信息还原等评估理念,基于对电网运行全过程记录,本文提出了过程化的理想调度评估方法,实现了对调度员决策水平的评估分析及各类外部因素影响程度的量化计算,为进一步提高电网调度运行的精益化水平提供了科学的手段与工具。最后,以实际电网的运行数据构造算例,验证了本文所提出方法的合理性与有效性。
In order to enhance the management level of power system operation, PJM power market operator proposed the Perfect Dispatch Evaluation Method (PDEM) in 2007. Compared to the traditional evaluation methods, PDEM incorporated the actual operation boundaries and determined a virtual “Perfect Dispatch Scheme” (PDS) from post hoc perspectives. In this case, the deviations between the actual situation and the PDS could be quantitatively analyzed. This paper further implemented the PDS into various process of power system operation, identified the critical influencing factors, and formulated the influencing mechanisms. Based on information restoration and process analysis techniques, a novel PDEM is proposed to identify the effects incurred by decision and non-decision factors, respectively. In the end, a numerical case based on real operation data is studied to testify the effectiveness of the proposed method.
公司创制章程条款研究

比较法研究 , 2015,
Abstract: 公司创制章程条款是体现股东或公司的意志,蕴含着不同于公司法规范的创新性,且能排除或代替公司法任意规范适用的自治规范。其性质具有契约与自治法规的兼容或并存性的法理基础。公司法对创制章程条款既留有余地又设有限制。创制章程条款是否有效,不但应有一般法上的判断标准,更应作个案化的深入思考。

云南某工程建设场地岩溶分布与形成机制

地质与勘探 , 2015,
Abstract: 近年来,随着经济的蓬勃发展,在岩溶区修筑建筑物越来越多,岩溶作为一种特殊的不良地质作用给许多工程建设带来困难。云南某大型工程建设项目在勘察阶段发现大量的溶洞,严重影响了该工程的地基施工。本文据场地岩溶区的详细勘察和钻孔资料,描述了岩溶表现形式、在平面上和垂向上的分布特征及其影响因素,并从研究区的地形地貌、地层岩性、地质构造、气象水文和新构造运动等方面研究了岩溶的形成机制,为岩溶地区工程建设中的灾害预防提供科学依据。
直线图解法在分析河流水团示踪试验数据中的应用

环境科学 , 1992,
Abstract: 在示踪剂的一级反应速率常数K1不为零的条件下,将反映水团示踪试验中示踪剂浓度变化规律的解析表达式进行适当变化,得到一直线方程。该方程的自变量和因变量中仅含有原始观测数据,直线常数中含有K1、D和u三个参数。故在通过直线图解法或线性回归法求出两常数后,在K1与u中有一个为已知时,即可求出另外两参数。
早熟沙打旺区域试验初报

华北农学报 , 1985, DOI: 10.7668/hbnxb.1985.04.006
Abstract: 沙打旺原产黄河故道地区,是豆科黄芪属多年生草本植物。在张家口坝下地区种植,表现耐瘠薄、耐干旱、抗寒冷、抗风沙,产草量高、草的品质比较好,是优良绿肥和牧草。但是,由于它要求较长的生长期(170~180天),较高的活动积温(3500~4000℃以上)。

Abstract:
本文从中山供电局工业客户用电行为着手,研究其用电行为特性和生产特点,实施错峰优化,在确保错峰效果的同时,降低对企业造成的影响,减少了企业的停电时间,比原方案更能得到工业客户的理解和支持配合,有效提升客户自觉错峰率,从而减少开展错峰工作所需要的人力物力,并通过优化错峰方案,争取将有限的电能用到对社会贡献最大的行业和企业。实施错峰优化后,错峰效率的提升将降低对工业客户强制停限电的频率;对客户提供差异化的方案,降低了对工业客户正常生产的影响,树立以客户为先,提供优质服务的形象。
Starting with industrial power customers’ behavior of Zhongshan Power Supply Bureau, this paper studies the electrical behavior and production characteristics, and implements staggering power consumption optimization. Then an optimization method is proposed, which could guarantee the peak load shifting effect, and at the same time could reduce the influence on users. In this way, peak load shifting could reduce outage time and get industrial customers’ understanding and support compared to the former way. And with the peak load shifting support system, manpower could be cut down. Based on the optimization of peak load shifting scheme, the limited power could be used in the most efficient enterprise. The improvement of peak load shifting will reduce industrial customers’ forced outage frequency as well as the influence on the normal production of the industrial customers, and help the power supply bureau put the customers first, providing quality services.
