摘要
本文介绍一种基于全数字电力系统仿真器的直流控保封装建模方法,利用软件提供的用户自定义模块功能,创建出一定数量的自定义模块来模拟实际的控保装置,这些自定义模块跟一次系统配合组建成直流控制保护模型。文中介绍了控制保护自定义模块的创建方法、溪浙直流封装建模过程和试验验证。由于控保模块的代码是由实际工程程序转化而来的,自定义模块内部控保逻辑的运行方式几乎与实际装置一致,所以模型的准确度会很高。通过试验测试和波形对比,证明了所搭建模型的准确性和精确性。采用该方法搭建的模型可以用于交直流大电网混合仿真中的直流计算,或单独用来进行现场事故反演和直流运维操作培训,具有很高的实用性。
This paper introduces a modeling method of DC control protection functions based on ADPSS.Using the user-defined module function provided by the software,a certain number of custom modules are created to simulate the actual control device.A DC control and protection model is builded by these custom modules and the primary system.The article introduces the creation method of the control protection custom module,the Xizhe DC packaging modeling process and test verification.As the code of the control and protection module is transformed from the actual engineering program,the operation mode of the control and protection logic inside the custom module is almost the same as the actual device,so the accuracy of the model will be very high.Through the test and waveform comparison,the accuracy and precision of the model are proved.The model built by this method can be used for DC calculation in the hybrid simulation of AC and DC power grids,or it can be used alone for field accident inversion and DC operation and maintenance operation training.It has high practicality.
