改革开放后,混合所有制改革在党的文件中已有20多年的酝酿和发展;党的十八届三中全会后,各级政府积极采取行动推动这个改革.然而,在企业层面,交易属性和交易成本决定了混合所有制改革难以大规模快速推进;在国家层面,混合所有制改革不是私有化,而是要在多种所有制经济"共赢同进"中完善社会主义基本经济制度,做强做优做大公有制经济.新时代的混合所有制改革应当是渐进式的、稳健的,而不是运动式的,更不是激进的私有化;混合所有制改革的模式应是多样化的,要积极探索真正体现初心的、适宜的改革模式.

针对县级供电企业安全生产标准化存在的问题,通过建设安全文化、开展安全培训等不断提高安全生产的主动性;开展县级供电企业的安全性评价提高安全生产标准化系统性;实施PDCA三级嵌套式循环实现安全生产标准化的持续性,夯实本质安全的核心四要素——队伍建设、电网结构、设备质量、管理制度,提高县级供电企业的本质安全水平.

公文是党和国家机关在领导党的事业和治理国家方面,用以表达意志、传递策令、沟通信息的文字工具和手段.当前,电力科研人员在公文写作方面存在基本要求不熟、文字表达欠佳的问题,严重影响了办文办事效率和企业形象.通过例举电力科研人员公文写作存在的部分具体问题,分析了问题产生的原因,提出了提高电力科研人员公文写作水平的建议.

为避免利用Java反序列化漏洞影响企业核心业务、产生重大信息安全事件,详细介绍了Java反序列化漏洞的背景、原理、漏洞利用方法及工具,通过一个具体实例给出利用该漏洞进行服务器主机系统提权的详细步骤,并提出了多种漏洞修复方法.

司法鉴定是一个高风险活动,电力司法鉴定机构需要在鉴定执业活动中控制各类风险,实现规范运作.本文运用风险控制管理理论,以问题为导向,探索如何实现规范管理,提出了广义的司法鉴定风险概念,主张控制司法鉴定风险是司法机构规范管理的核心目标.实践中要咨询专家,调研兄弟电力司法鉴定机构,借鉴先进管理经验,寻找防范鉴定风险的措施和途径.确定了规范管理的六个重点环节,建立并逐步完善工作流程和制度体系.

本文介绍了人才当量密度指标,以人才当量密度模型分析为基础,针对性地提出了提升人才当量密度的有效措施,在两年来的实践过程中提高了人才当量密度指标,全面提升了员工队伍整体素质,为加快国家电网公司"两个转变"和深化"三集五大"体系建设提供了有力支撑.

The article introduces some particular measures for two boilers-one steam turbine unit commissioning start under PG6111FA gas turbine with high load.Especially it illustrates how to deal with gland steam spray,inputting two boilers,air cooling condensate waving.

The vacuum system fault of steam turbine No.2 of L Power Plant in Indonesia was introduced.The reasons caused the vacuum system fault were diagnosed and analyzed.Using the filling water method and the Helium mass spectrum leakage detector to find the leakage point of the vacuum system,the especially big leakage point was found in lower half casing of low pressure cylinder.The effective measures were adopted,and the condenser vacuum leakage fault does not occur again.

Measuring and calculating the labyrinth leakage between the HP and IP turbines for HP&IP combined turbine in reheat cycle can reduce the heat rate uncertainty of the performance test.By analyzing adopted performance test codes and practice experiences,advise this measuring method be applied to all performance tests.The thermodynamics,measuring method and calculating procedure are presented.An application for performance test is introduced.

The turbine has the problem that the upper and lower casing temperature difference is too big during hot start process.The paper point out that there is design defect in the drainage system and proposes the modification suggestions.After modification,the temperature difference is about 20℃ during hot start.

Based on the commissioning result of isolated network power plant in Aleppo cement plant Syria,analysis the characters and difficulty,put forward The key commissioning technology for isolated network power plant,provide precautions in period of commissioning,some technique methods are presented for reference.

By using helium mass spectrometer leak detector,analyzing the variation from relationship between load and vacuum value,using helium diffuse method,abig leak was found out in one of the Hubei 600MW turbine vacuum system,saved social and economical benefits.

The uncertainty calculation method for the gas turbine performance tests is discussed and analyze the ralationship of heating rate and every parameter uncertainty.The measures for controling the uncertainty is introduced also.
