precision of voltage regulation meaning in English

稳压精度

By the simulation it has been indicated that the nec + pid excitation control theory does not only keep the stability of generator in the transient process but also improves the precision of voltage regulation
仿真结果表明：与传统的励磁控制相比， “ nec + pid ”励磁控制方法不仅能够提高发电机在暂态情况下的系统稳定性，而且具有较高的电压控制精度。
In this paper , after entirely introduction of the development of generator excitation control theory and compare of all kinds of excitation control method , the nolinear excitation control theory with using the differential coefficient geometry theory is presented and its shortage of lack of precision of voltage regulation is indicated . combining traditional pid excitation control theory , the nolinear excitation control theory is improved effectively and the nec + pid excitation control method is offered
论文详细地介绍了各种发电机励磁控制方式，在比较分析了各种励磁控制方式特点之后，给出了运用微分几何理论实现发电机非线性励磁控制的方法，同时指出现有非线性励磁控制方式对电压控制精度不高的问题，结合传统pid控制对非线性励磁控制方式进行了有效的改进，提出了“ nec + pid ”相结合新的励磁控制方法。
