Analyzing the Current Situation of Employment Quality in China

The current situation of employment quality in China allows no optimist during the period of economic transition. The disequilibrium is the most stressing characteristic in China＇s employment quality. The disequilibrium of this kind of level of the employment quality not only reflects among the areas where the economic development levels are different, but also reflects more differences of the employment quality due to the differences of the worker＇s identity in the labor market. At present, the problems of employment quality in China are mainly reflected in the labor contracts, working time, labor remuneration, job stability, safety in production, job hygiene, social security, and the respects of basic human rights and participating in the democratic management by the laborers, etc. During the economic transition period, the work relation fields in China appear some special colonies, such as the farmer＇s colony, the colony of ownership transformed enterprises, the colony of flexible persons who obtain employment themselves, whose employment quality demonstrates the questions of some peculiar ones and need special concern.

针对LCL型并网逆变器输出电流质量容易受电网电压背景谐波及在弱电网条件下电网阻抗的影响,提出一种附加虚拟阻抗的LCL型并网逆变器电流扰动观测控制方法。首先,在常规双闭环控制的基础上引入扰动观测器,将电网电压背景谐波视为系统外部扰动,利用扰动观测器实时估算出扰动量并前馈补偿动态消除扰动对系统的影响;其次通过阻抗分析法来分析弱电网系统中电网阻抗引起稳定性下降的问题,在电流扰动观测控制方法的基础上再加入虚拟阻抗进行优化设计,使得并网阻抗在阻抗交截频率较大范围内变化时的相角裕度仍然大于系统所约束的稳定裕度。仿真对比结果表明,所提方法在保持良好的电流质量的同时提高了系统对电网阻抗的鲁棒性。
