变压器风冷变频控制的发展
泵与风机类负载采用变频调速技术可以节能30% 左右[1]。发电厂和变电站中的变压器大多采用强迫油循环风冷却或自然油循环风冷却运行方式。常规运行模式为根据变压器顶层油温整组投切工频运行的循环油泵和风机，在昼夜温差和季节温差较大的地区，或者用电负荷波动较大的地区势必由于过冷却造成能源的浪费。
The pump and fan type load can be saved by about 30% [1] by using variable frequency speed regulation technology. Most transformers in power plants and substations are operated by forced oil circulating air cooling or natural oil circulating air cooling. The conventional operation mode is to switch the circulating oil pump and fan according to the oil temperature of the top layer of the transformer, which will cause energy waste in the area with large temperature difference between day and night, seasonal temperature difference, or in the area with large fluctuation of electric load.
1985年日本某公司最先提出了根据变压器负载以及环境温度变化的变压器风冷变频运行方案，并在理论上进行了节能分析和试验验证[2]。
In 1985, a Japanese company first put forward a transformer air-cooled frequency conversion operation scheme according to transformer load and environmental temperature changes, and carried out energy-saving analysis and test verification in theory [2].
1998 年国内东北电力学院崔实、赵景林在《节能》期刊上发表了“VVVF 变频器在变压器冷却系统应用的节能效果分析”文章，在理论分析与试验的基础上，得出了在变压器冷却系统中采用变频调速可以节能1/3 以上的结论。
In 1998, Cui Shi and Zhao Jinglin of Northeast Electric Power College published the article "Energy Saving Effect Analysis of VVVF Inverter in Transformer Cooling System" in the Journal of Energy Conservation. On the basis of theoretical analysis and experiment, it is concluded that using frequency conversion speed regulation in transformer cooling system can save more than one third of energy.
2007 年吉林供电公司首次在某变电站进行变压器变频风冷的现场运行试验，试验结果表明安装变频式变压器风冷控制系统后，变压器风冷装置日平均耗电量约为原运行方式下的35%。
In 2007, Jilin Power Supply Company conducted the first field operation test of transformer frequency conversion air cooling in a substation. The test results show that the average daily power consumption of the transformer air cooling device is about 35% of the original operation mode after installing the frequency conversion transformer air cooling control system.
此后的10 余年中，变压器风冷变频调速装置硬件系统日臻完善，软件控制算法也更趋合理。随着智能电网和数字化无人值班变电站的发展，对变压器辅助系统的可靠性和稳定性的要求也越来越高，泵与风机变频运行过程中的电磁兼容问题越来越突出，制约了该类产品的应用和推广。
In the next 10 years, the hardware system of the transformer air-cooled variable frequency speed regulating device has been improved day by day, and the software control algorithm has become more reasonable. With the development of smart grid and digital unattended substation, the requirement of reliability and stability of transformer auxiliary system is becoming higher and higher. The electromagnetic compatibility problem of pump and fan in frequency conversion operation is becoming more and more prominent, which restricts the application and promotion of this kind of products.
