静止式进相器可行性项目分析报告 Feasibility analysis of stationary phase advancer 一、项目的意义和必要性 随着电能的广泛应用，电力的质量却成为日趋严重的问题。尤其大型电机大规模使用，带来的功率因数下降已成为电力系统的主要问题。据估算功率因数的下降每年给全国电网造成的能耗损失，相当于四座三峡大坝。这些给全社会造成直接的损失非常大。 1. The significance and necessity of the project With the extensive application of electricity, power quality has become an increasingly serious problem. In particular, large-scale using of large power motors which bring the power factor drop have become the main problem of the electricity system. According to estimates the power factor of the energy loss per year to the national grid drop caused by the equivalent of four of the Three Gorges project. These great cause directly damage to the whole community. 相关领域国内外技术现状和发展趋势 虽然功率因数补偿国内外都有相应的公司和机构进行这方面工作，也有很多产品面市，但是对电动机的功率因数补偿全是从电动机的外部进行补偿，电动机定子侧的无功电流没有降低。国内目前普遍使用的是电容、自激（旋转）式进相机对电动机进行补偿。 2. The technical status and trends in the related domestic and oversea fields Although the power factor compensation in the domestic and oversea have carried out the appropriate companies and organizations working in this area, there are many products available, but the motor power factor correction to compensate all from outside of the motor, the motor stator reactive current is not reduced. China is now widely used in capacitors self-excited (rotation) phase advancer to compensate for the motor. 解决方案 无环流静止式进相器是本公司自行研制开发的新一代高新技术产品，是一种专为大中型绕线式异步电动机设计制作的就地无功功率补偿装置。它串接于电机转子回路，用以提高电机的功率因子，降低定子电流，降低电机温升，降低电机及电网的无功及有功损耗，改善电机的运行状况，延长电机的使用寿命，对节约能源、降低单位产品成本，提高企业的经济效益具有重要意义。 3. The solution No circulation static phase generator is a new generation of high-tech products fully developed by our company, is a specially designed for medium and large wound type of asynchronous motor, it is a no-power consumed and just-in-place compensation device. It is connected in series with the motor rotor circuit to improve the power factor of the motor, reducing the stator current, lower motor temperature, reduce reactive and active power loss of motor and electricit
