【摘要】：随着电力市场竞争日益激烈和对节能减排问题的重视程度不断提高,对节能技术需求也不断提高。变频调速作为理想的节能调速技术,借助高压大功率电力电子技术和计算机控制技术的迅速发展,在电厂风机、水泵等重要辅机上得到了广泛应用,为电厂节能降耗、提高经济效益、降低设备冲击、降低设备故障率起了重要作用。本文从分析高压变频器在电厂应用产生的实际效果,以及影响应用效果的关键问题出发,提出了在高压变频器应用项目中实施设备监理的必要性。根据高压变频器在电厂应用项目的特点,提出了成套设备监理过程中投资决策、质量控制、安全管理应作为监理重点,从对高压变频器适用性、可靠性、节能效果、财务分析等具体问题入手分析了投资决策过程。针对高压变频器的设计、采购、制造、安装及调试等设备形成全过程质量控制的范围、对象、内容、原则等设备监理技术的具体应用。并结合发电厂安全管理对变频器安装过程中的危险点进行分析,制定了具体防范措施。对此类成套电气设备工程控制投资风险,提高设备工程质量,保证施工安全具有重要意义。对设备监理行业向更专业化、分工更细化的方向发展,起到了极大的促进作用。
[Abstract]:With the increasingly fierce competition in the power market and the increasing attention to the problem of energy saving and emission reduction, the demand for energy saving technology is also increasing. As an ideal energy-saving speed regulation technology, frequency conversion speed regulation has been widely used in power plant fans, pumps and other important auxiliary machines with the help of the rapid development of high voltage and high power electronics technology and computer control technology, which plays an important role in energy saving and consumption reduction, economic benefit improvement, equipment impact reduction and equipment failure rate. Based on the analysis of the practical effect of high voltage frequency converter in power plant and the key problems affecting the application effect, this paper puts forward the necessity of implementing equipment supervision in the application project of high voltage frequency converter. According to the characteristics of the application project of high voltage frequency converter in power plant, this paper puts forward that investment decision, quality control and safety management should be regarded as the key points of supervision in the process of supervision of complete sets of equipment, and analyzes the process of investment decision from the aspects of applicability, reliability, energy saving effect and financial analysis of high voltage frequency converter. Aiming at the design, purchase, manufacture, installation and debugging of high voltage frequency converter, the concrete application of equipment supervision technology, such as the scope, object, content and principle of equipment supervision in the whole process is formed. Combined with the safety management of power plant, the dangerous points in the installation process of frequency converter are analyzed, and the concrete preventive measures are worked out. It is of great significance to control the investment risk, improve the quality of equipment engineering and ensure the construction safety of this kind of electrical equipment engineering. It has played a great role in promoting the development of equipment supervision industry in the direction of more specialization and more detailed division of labor.
