【摘要】：随着国家经济的快速发展,我国的电力系统也发展十分迅速。电力市场逐步实施并形成了“厂网分开、竞价上网”的基本局面,大电网互联的战略也已经逐步展开。因此,研究机组与电网之间的协调运行问题,即机网协调运行问题,对整个电力系统的安全性与稳定性都有重大的意义。本文研究了火电厂动力系统以及电网系统的建模,建立了一个厂网联合仿真平台,并运用该仿真平台对机网联合运行系统进行了仿真分析。本文研究的具体工作如下： 1.对火电厂动力系统的各个主要元件进行了数学分析,推导出了它们的数学模型,并且基于火电厂动力系统的仿真引擎SimuEngine搭建了火电厂动力系统的各个主要部分的仿真模块,建立了火电厂动力系统的仿真模型。 2.对电力系统的各种主要元件,如同步发电机、变压器、输电线路和负荷进行了数学模型的推导。基于RTDS电网实时数字仿真器搭建了一个完整的电力系统模型,以用来对电力系统进行仿真分析。 3.阐述了实现火电厂动力系统仿真器SimuEngine与RTDS电网实时数字仿真器之间通信的两种方法,即基于RTDS的GTNET/DNP3.0规约方式的通信方法和基于RTDS电网实时数字仿真器的I/O模块的模拟量通信方法,并且利用C++语言开发了基于RTDS的GTNET/DNP3.0规约通信的接口软件,成功实现了火电厂动力系统仿真器SimuEngine与RTDS电网实时数字仿真器之间的通信。 4.利用厂网联合运行仿真平台对机网联合运行系统进行仿真分析,验证了厂网联合仿真平台的运行可靠性以及建立的火电厂动力系统和电网系统的模型的合理性和准确性。
[Abstract]:With the rapid development of national economy, the power system of our country is also developing very rapidly. The power market has gradually implemented and formed the basic situation of "separation of power plants and networks, bidding to surf the Internet", and the strategy of interconnection of large power grids has also been gradually launched. Therefore, it is of great significance to study the coordinated operation between the unit and the power grid, that is, the coordinated operation of the power network, for the security and stability of the whole power system. In this paper, the modeling of power system and power grid system of thermal power plant is studied, and a joint simulation platform of power plant and network is established, and the joint operation system of power plant and network is simulated and analyzed by using the simulation platform. The specific work of this paper is as follows: 1. The mathematical analysis of the main components of the power system of thermal power plant is carried out, and their mathematical models are derived. based on the simulation engine SimuEngine of the power system of thermal power plant, the simulation modules of each part of the power system of thermal power plant are built, and the simulation model of power system of thermal power plant is established. two銆，
