多机电力系统暂态稳定性及提高暂态稳定性措施分析研究

Application and Design Analysis of Programmable Controller in Interlocking System of Petroleum Coking Unit

随着国民经济和科技水平的快速发展,化工行业成为人们生活工作中密不可少的一部分,其中电力工业为化工行业提供动力来源,化工电力系统规模不断扩大和复杂,逐渐形成远距离、大容量和高压输送的混合电力网络系统,安全、稳定可靠对电力系统的运行至关重要。如遭受破坏极其容易崩溃甚至瓦解,其结果严重时将导致大面积停电及巨大经济损失。因此,研究暂态稳定性的项目非常重要。

With the rapid development of the national economy and scientific and technological level,the chemical industry has become an indispensable part of people's life and work,in which the power industry provides power sources for the chemical industry,the scale of the chemical power system continues to expand and complex,and gradually forms a long-distance,large-capacity and high-voltage transmission of the hybrid power network system,safe,stable and reliable for the operation of the power system is crucial.If the damage is extremely easy to collapse or even collapse,the result will lead to a large area of power outage and huge economic losses.the project to study transient stability is very important.
