【摘要】 电力电子技术是能够给电力工业带来革命性进步的新技术，而电力电子试验室的建设是电力电子技术在电力系统中工程化应用的先决条件，按照IEC有关标准，各类电力电子实用装置均对相关的实验条件提出了具体的要求。同时，试验装备(耐压试验装置、温升试验装置、过电流试验装置以及合成“全工况”试验装置)的建设又将进一步促进电力电子装置实用化进程。 目前电力电子试验室建设的首要任务就是完成温升试验装置开发工作。这是由温升试验装置的核心与基础地位所决定的。因为它一方面要负责被试品的温升试验，即测试被试品在正常工作情况下的温度性能指标。另一方面它还将是进行过电流试验、合成“全工况”试验的辅助设备，没有它将无法进行这两项试验。因此相对而言温升试验装置更具基础性和必要性。 温升试验装置实际上就是一个可提供不同等级大电流的单相、高压试验电源。该试验电源一次回路的设计原理较为简单。首先通过一个转换变压器将三相电源转换为单相电源，然后通过单相温升试验变压器向被试品(高压阀)提供不同等级的高电压、大电流。温升试验装置的二次部分，即测控系统作为试验装置的神经中枢，对试验装置自身的性能和调节特性都有十分重要的作用，特别是温升试验回路的测控系统必须具备较大的控制灵活性，因为它不仅仅是用于温升试验，还要提供辅助接口作为过电流试验、合成“全工况”试验的辅助部分协同工作。经过综合比较我们决定采用西门子公司的可编程序控制器(PLC)技术和PROFIBUS现场总线技术来实现温升试验装置的测量、控制功能。 最后依据温升装置在验收调试过程和TCSC TE板触发功能的开发调试等实际运行过程中收集的大量试验数据、波形图文件进行了充分的理论分析、过程判别，从而对温升试验装置做出一个全面的、客观的性能评估。更多还原

【Abstract】 Power electronic technology is a new technology which can bring innovatory progress in power industry. And the building of the power electronic lab is precondition if we want to widely use the power electronic technology in power system. According to IEC standard,power electronic equipment also advance different request on testing condition. The building the power electronic testing equiment (such as high voltage tester,temperature tester,exceed current tester,"full state" tester)will help to speed the development of the power electronic equiment.Now the primary task to build the power electronic lab is to complete the temperature tester, Because the temperature tester play an important role in the power electronic lab. On the one hand the temperature tester can test the high voltage valve’s temperature parameter, On the other hand the temperature tester can help to complete exceed current test and "full state" test. Without the temperature tester, We can not do the exceed current test and "full state" test. So the temperature tester is more important than other tow tester.In nature the temperature tester is a power supply which can supply great current and high voltage. The design principle of the power supply is relatively simple. Firstly we can change three-phase power into single-phase by a transition transformer, Then we can supply different class’s great current and high voltage to the high voltage valve. The measurement and control system is the nerve centre of the temperature tester. By carefully thinking we decide to use the SIMATIC PLC and PROFIBUS field bus technology key i the measurement and control systemAt last,According to the data and chart that we get during the testing procession we can get a impersonal estimation of the temperature tester.更多还原
