在风险叠加的现代社会中,一个情感关联、利益共融式的社区共同体格局对城市社区善治达成至关重要。既有研究主要从结构、组织和能动者维度解释社区共同体的生成,忽视空间生产对社区共同体生成的重要影响。基于上海市G社区老旧小区加装电梯这一公共空间生产过程案例,深描社区共同体生成的具体过程,探究社区共同体生成的内在机制。研究将空间生产操作化,指出空间生产运作过程内蕴着物理空间、社会空间和情感空间三重生产过程。其中,物理空间生产通过产权关联的机制促成利益共同体生成,社会空间生产通过多方参与机制促成治理共同体生成,精神空间生产则通过认同凝结机制促成情感共同体生成。研究提炼出系统分析空间生产助推社区共同体生成的分析框架,并进一步讨论了中国公共空间生产的治理面向及其对重建“附近”的重要意义。

柔性直流配电网故障特征复杂,快速可靠的故障保护方法是柔性直流配电网亟需突破的关键技术。基于此提出了一种基于直流线路限流电抗器暂态电压皮尔逊(Pearson)相关系数的直流配电网纵联保护方法。首先,分析了区内外不同故障类型下直流线路两端限流电抗器暂态电压的特征差异。其次,利用正、负极线路电压的变化率构成保护启动判据,通过直流线路两端限流电抗器暂态电压的Pearson相关系数识别区内、外故障,并利用直流线路正负极电压变化率间的正负关系设计故障选极判据。最后,在Matlab/Simulink仿真软件中搭建柔性直流配电网仿真模型验证所提保护方法的可行性。结果表明所提保护方法能满足柔性直流配电网保护速动性和选择性的要求,且耐过渡电阻能力强,受通信延迟影响小,具有一定的抗干扰能力。
