国家经贸委节能信息传播中心于2000年12月6日在昆明召开数控就地TSC(晶闸管控制电容器)动态无功功率补偿技术推广会,向冶金、煤炭、有色、化工、造纸等行业推广这项先进节能技术。据电力电子专家介绍,我国与发达国家相比,用电水平还很低,特别是大量感性负载的应用使得电网供电能力下降。在功率因数为0.75时,电网需提供高于负载有功功率33%的容量。为此,国家出台了很多政策,鼓励企业采取措施对无功功率进行补偿,以提高功率因数。据测算,功率因数从0.75提高到0.95,相当于提高供电能力20%,可有效发挥现有的供电能力,达到节能环保的目的。 数控就地TSC动态无功补偿技术是我国开发的一项高新技术,采用晶闸管控制电容器以10毫秒速率无电流冲击直接投切电网,与目前国际流行的TCR补偿技术相比,成本低,自身能耗小,能耗仅相当于整个系统容量1%左右,节电效果十分明显,具
On December 6, 2000, the State Economic and Trade Commission for Energy Conservation Information Dissemination Center held a promotion meeting of dynamic reactive power compensation technology of TSC (Thyristor Control Capacitor) in Kunming, promoting the project to metallurgy, coal, nonferrous metals, chemical industry and papermaking industries Advanced energy-saving technologies. According to experts in power electronics, compared with the developed countries in our country, the level of electricity consumption is still very low. In particular, the application of a large number of inductive loads makes the power supply capacity of the power grid decrease. At a power factor of 0.75, the grid needs to provide more than 33% of the active power of the load. To this end, the state has promulgated many policies to encourage enterprises to take measures to compensate for reactive power in order to improve the power factor. It is estimated that the power factor increased from 0.75 to 0.95, equivalent to 20% increase in power supply capacity, can effectively play the existing power supply capacity, energy saving and environmental protection purposes. NC in situ TSC dynamic reactive power compensation technology is developed in China a high-tech, the use of thyristor control capacitor to 10 ms without current surge directly switch the power grid, with the current international popular TCR compensation technology, low cost, its own energy Consumption is small, energy consumption is only about 1% of the entire system capacity, energy-saving effect is very obvious, with
