内蒙古苏里格热调峰燃气电厂同期系统设计.doc

摘要 根据内蒙古苏里格供热调峰燃气电厂电气主接线图，设计内蒙古苏里格热调峰燃气电厂的并列系统，使之具有手动集中准同期、屏柜操作集中自动准同期、远方操作集中自动准同期、自动调频、自动调压、自动电压切换、自动操作回路切换等功能。 同期操作（或同期并列）是将同期发电机投入到电力系统参加同期并列运行的操作，同期操作是借助于同期电压和同期装置实现的。将两个单独运行的电力系统通过将两者间的联络断路器合闸，从而使这两个原来单独运行的电力系统并列在一起运行的操作，称为电力系统的并列操作。完成同期操作是一个复杂、重要的操作，一般均由自动准同期装置完成，本次设计需要用到江苏国瑞自动化工程有限公司的WX-98F微型准同期装置及YAC-2000型同期智能操装置，以完成苏里格供热调峰电厂同期系统设计。 关键词 电力系统 同期 并网 Abstract Inner Mongolia under the Sulige gas heating peak shaving main electric power plant wiring diagram, design Inner Mongolia Sulige gas thermal power plant tied for peak shaving system, so that a manual-focus the same period, the counter-screen operation on automatic synchronization, afar Operating on automatic synchronization, automatic FM, automatic voltage regulation, automatic voltage switches, automatic circuit switching capabilities.  Over the same period operation (or tied for the same period) will be input to the same period generator power system running parallel to participate in the same period in the operation, is the help of the same period in the same period operating voltage and devices to achieve the same period. The operation will be two separate power systems through contact between the breaker switch on, so that the original two separate operating system tied together the power of running the operation, known as the power system of parallel operations. Completion of the same period operation is a complex and important operation, the general automatic synchronization devices are completed, this design need to use Jiangsu Guorui Automation Engineering Company Limited, the micro-WX-98F over the same period installations and YAC-2000 over the same period of smart devices parade , To complete the Sulige heating peak shaving plant the same period in system design. Key word power system the corresponding period juxtapose 1.绪论 1.毕业论文的意义 撰写毕业论文是检验学生在校学习成果的重要措施，也是提高教学质量的重要环节。大学生在毕业前都必须完成毕业论文的撰写任务。申请学位必须提交相应的学位论文，经答辩通过后，方可取得学位。可以这么说，毕业论文是结束大学学习生活走向社会的一个中介和桥梁。毕业论文是大学生
