|
摘要
本文以巴陵石化热电事业部110kV线路保护为研究对象,阐述了以关口保护为重点的项目的实施对局域电网可靠性的提高所起的重要作用。
本文首先介绍了巴陵石化热电事业部电网的基本情况及负荷受季节性的影响比较大的特点,以两起典型的电网事故为例,说明了110kV线路可靠性的提高对巴陵石化公司的重要意义。
论文简要介绍了微机型保护装置的基本结构,各部分的原理及作用,结合基本的数学理论说明其实现过程。
论文以电力系统的动静稳定理论为依据,简要说明了小系统不稳定的原因及防范措施,以巴陵石化的一起典型事故为例分析了造成这起事故的原因,提出巴陵石化小系统与电力网连接线在继电保护与安全自动装置上存在的主要问题是故障情况下不能完全快速地动作,故障切除后负荷不能快速平衡,小系统不能快速地与电网并列等,并提出了解决上述问题的方案。
论文介绍了几种SEL继电保护装置基本功能,说明了其在项目实施中的开发应用情况,以及改造实施后解决的几个关键问题,以实例说明本研究课题的实施对巴陵石化公司安全和效益上所起到的巨大作用。
本课题的研究与实际应用情况对同类自备电厂的稳控方案有一定的指导意义,当电网出现低频时,本研究课题以有利的原则确定是否与电网解列,在解列的逻辑上设置了逆功率闭锁;将传统的减载演变为负荷联切,联切负荷的大小根据当时的进电负荷大小预行设定,可以使内部电网的功角在故障发生时不产生大的变化,减小系统振荡的可能性;对保护装置重新进行逻辑编程,把备用电源自投和线路重合闸进行有效结合,使之更符合自备电厂的要求。
In this paper,the Baling petrochemical power plant 110 KV line protection for the study, described as a gateway to protect the implementation of the project focused on improving the reliability of power grids local playing an important role.
In this paper, the basic-owned power plants and seasonal load influenced by the characteristics to a typical grid two incidents illustrate how the 110 KV lines improve the reliability of the company's significance.
Papers briefly introduced microprocessor-based protection device, the basic structure of the part of the principle and effect, the combination of basic mathematical theory that the implementation process.
Papers to the static and dynamic stability of the power system based on the theory, a brief description of the reasons for the small system instability and precautionary measures to the Baling petrochemical company as an example of a typical incident of the cause of this accident was caused, the company is small grid connected with the power grid lines in the protection and automatic safety device on the main question is: under fault conditions can not be completely rapid movements fault after resection can quickly load balance on the system can not be quickly tied and power grids, etc.. And proposed solving the above problems.
This paper introduces some basic functions SEL protection device, described in the implementation of its projects in the development and application of, and the transformation of the solution after the implementation of several key issues, illustrates the implementation of this project on the safety and effectiveness of the company to the great role played by.
The research projects in the actual application of the same-owned power plant stability control programmes have a certain significance, when a low-frequency power grids, the topic of this study to determine whether the principle of benefiting out of the grid, out of the logic set up a reverse power atresia; will be contained by traditional evolution of the shear load, the load-shedding was in accordance with the size of the electric load into pre-set size, the internal power grid will enable the power angle in the fault does not have a big change, oscillation system decreases the possibility of re-protection device logic programming, and for standby power lines since the reclosing to effectively combine to make them more consistent with the requirements-owned power plant
