In this project, we make research in the measurement of the power-net which plays an important role in the electrization railway system. Applying the theory of CCD and CCD devices, we design a set of optics system, and using the MCS-51 as the controlling kernel. To transmit and store the data, we utilize the technique of IrAD and serial transmission.

摘要本论文首先探讨了当前电气化铁路接触网测量方面的问题，并针对这些问题研究了CCD理论及CCD器件在光电检测中的应用，同时根据该理论设计出一套光学系统，并以在智能检测领域中应用很广的MCS-51微控制器为控制核心，运用红外及串行传输技术，实现了数据的检测及存储。

The main products are developed from the single HL series HVDC Current Source Power Supply used in electrostatic deposition to the whole set of electrostatic dust precipitation (electrical demisting, electrical tar precipitation) high and low voltage electrical control system, and the manufacture and debugging of the related process-control system. We engage in making overall solutions to the electrical control system accordingly for our customer.

But going with the power system"s development, many new excitor models, PSS models, turtine models, governor models and boiler models appear. It"s not satisfied to increase new interior models in model library. Furthermore openness is a basic characteristic of DTS. So it is very important to constitute a very high efficient, convenient and universal tool for users who can set up new models by themselves.

然而随着电力系统的发展，各种新型的励磁系统模型、PSS模型、原动机模型、调速器模型、锅炉模型不断出现，继续在模型库中新增固定模型的做法显然难以满足众多用户的要求，而DTS的一个基本要求就是开放性，因此建立一个高效、方便的通用平台，以方便用户自行构建动态仿真的模型就显得非常重要。

Users may also need to set power factor, the minimum value of over-voltage parameters.

同时用户可根据需要设定功率因数上、下限，过电压值等参数。
