合环与解环合环与解环loop closing and openinghehuon yu Jlehuon合环与解环(loop elosing and opening)在并列运行的电力系统中，将发电厂或变电所间的输电线路连接成环状网络或将环状网络解开。合环运行能提高电力系统运行的灵活性、经济性、可靠性。可以利用先合环后解环的办法将发电厂或变电所在不解列和不停电的情况下由一个电力网切换到另一个电力网。解环运行常是为了减小电力系统短路容量和满足系统运行方式的要求。合环若合环点两侧有相位差和电压差，合环后会出现环流，可能引起环路内的电力设备过负荷或使继电保护装置动作而跳闸。在电力系统实际运行中，电压差允许在10%以内(500 kV电网应在5环已内)，相位差在5o以内合环即可，但由于系统结构不同，有的系统合环相位差允许100~150。在合环前，对合环环流一般都要进行计算，做模拟或实时工况合环试验，根据计算和试验结果确定合环时允许的相位差和电压差。进行合环操作时，若相位差和电压差不符合允许条件，则必须调整到允许范围内。解环解环时要尽量减小解环点的有功功率和无功功率，以免解开环网时功率和电压的变化太大，引起电力系统发生异常或故障。
