混合式光纤电流互感器电源的研究
|
摘要
电流互感器作为电力系统中的重要设备，对电力系统的正常运行和电力的精确计量有非常重要的作用。随着国民经济的发展，新的供电电压等级不断提高，系统的测量和保护精度要求不断提高，电子式电流互感器替代传统的电磁式电流互感器是必然的趋势。混合式光纤电流互感器就是其中一种，但是它属于有源式的，高压侧电子、光电子器件的供能问题就成了要解决的关键问题。
本文针对目前光电混合式电流互感器的高压侧电源的要求，提出了光推动和在线式电源两个方案。对于光推动电源由于目前激光光源寿命短以及成本高的原因，仅提出了理论解决方案。对在线式供能方案提出了理论依据和电路实现。我们根据电磁感应原理，用线圈直接从高压母线上提取能量，但是母线电流变化范围大，根据安培环路定律，采用补偿方式，将多余的母线电流通过补偿绕组补偿掉，使激磁电流保持不变，各电源绕组感应电势保持相对稳定。补偿绕组的电流大小通过控制电路控制，控制电路的信号通过控制绕组采样于母线。
实验证明，采用这种方法设计的在线式电源，能使混合式光纤电流互感器可靠工作，并在4台样机中应用。
As important equipments in electric power industry, current transducers play a primary role for working well and calculating precisely in power supplying system. With the development of national economy, new high voltage level emerges continuously, and high accuracy of calculation and protection are demanded increasingly. It is an unavoidable trend that electric current transducer substitutes the old electromagnetic current transducer. Hybrid fiber current transducer is one of the electric current transducers.It needs power supply to ensure the electric and photoelectronic component in high-voltage side to run,so the power supply becomes the key problem.
In the paper aiming at the demand of power supply in the passing hybrid fiber current ,we lodge two projects:laser-driving and online to provide power. Because the life of lasers is too short and the cost is too high, to the laser-driving power supply,we only put forward the resolvent in theary. To the online to provide power ,not only do we biring out the theory but also provide the really circuit.Based on the theory of electromagnetic induction ,the power supply draw the energy from the power line directly.But the range of power line current is so wide, according to the law of ampere rounding circuit, to keep the exciting magnetism current and induced potential on the power windings steady ,we make use of another winding to compensate the redundant current.The compensatory current is controlled by controlling circuit and the controlling signal come from the power line by the controlling winding.
The experiments show that adopt this on-line power supply the hybrid fiber current transducer can run reliably.And we have apply the power supply to four transducers.
