在变电运行总,电气设备种类繁多,精密度、复杂度越来越高,愈加趋向于自动化、智能化.变电运行中一旦发生电气误操作,就很可能造成较为严重的影响,因此,加强研究电气误操作问题至关重要,电力单位应高度重视,积极采取有力预防和控制措施,防止发生变电运行误操作事故.
In recent years,the pace of development of China's economy continues to accelerate,with the rapid economic development,energy use has become a problem of the state,society,business and the people of common concern.Electricity supply is also facing energy shortages,and even various provinces and cities take different levels of power cuts to control electricity consumption.To solve the power problem of energy shortage,the state not only to speed up construction of power,but also to pay attention to the economic operation of power systems.Which discusses the economic operation of transformer substation is very important,is an important measure to save energy.From the economic significance of the transformer operation mode and control systems stand the test of this issue for discussion.
结合中部某地区电网2010发生的一起雷击线路导致雷电渡侵入变电站，断路器遭受雷击后绝缘损坏，并且导致变电站110kV系统失压事故。分析得出输电线路临近变电站区域遭受连续重复雷击而导致断路器过电压损坏的主要原因，并提出相应的防范措施。
文13北块沙三中油藏是一个极其特殊的低渗低阻油藏,随着油田的开发,层间矛盾加剧,开发效果较差,采收率极低。本文详细论述了气举转抽、大型水力压裂改造储层、加密井部署三种工艺在该区块的研究和应用,大大提高了该区块的采收率,从而为同类型油藏的开发提供了可靠的依据。
油井计量准确度关系到技术人员对油井生产的把握度,解决好油田井口计量问题是提高管理水平的关键,同时也是下步措施挖潜的前提保证,我们从计量的原理方法与器具入手经过现场。实验应用对比理论,通过改进工艺流程提高油田计量准确度。
文东油田属典型的高温高压低渗油藏,油层埋藏深,油井开采过程中基本上都进行过压裂改造,加之含盐高,套管损坏严重,本文较详细介绍了文东油田的井况防治技术。
文东油田是一个极其特殊的油藏,具有油藏埋藏深;异常高温、高压;高油气比;低渗透率等特点。在开采工艺方面遇到过很多难题,本文较详细的介绍了文东油田在气举、压裂、高压分注、调剖、解堵、堵水等工艺技术成功应用,为文东油田提高油藏开发水平提供了技术保障。
