电力系统无功功率平衡电力系统无功功率平衡reactive power balance of electric power system d旧n}1 xl飞ong wtjgong gong}。P{ngheng电力系统无功功率平衡(reaetive powe:bal-anee of eleetrie power system)根据电源发展规划和电力网发展规划、进行无功功率平衡计算，使系统的无功电源所发出的无功功率与系统的无功负荷相平衡。其目的在于维持各种运行方式下电力网各点的电压水平，确定无功补偿装置的配置及型式。 无功功率平衡原则按地区并按电压等级对无功电源和无功负荷进行平衡，即避免经长距离线路或多级变压器传送大量无功功率，以降低电力网损耗，实现经济运行.进行无功平衡时尚需考虑随负荷值的变化应具有的调节能力。 无功电源及无功负荷进行无功功率平衡时，应考虑无功电源和无功负荷两个方面。其中无功电源包括:①发电机发出的无功功率;②系统无功补偿设备;③110 kV及以上电压架空线路及各级电压电缆的充电功率;④从电力网外可能输人的无功功率。无功负荷包括:①系统用户无功负荷，主要是异步电动机无功负荷;②线路和变压器的无功损耗;③并联电抗器消耗的无功功率;①发电厂厂用无功负荷;⑤晶闸管，包括直流输电，在整流和逆变时吸收的无功功率。(见电力系统无功负荷) 无功备用容量进行无功功率平衡需要留有一定的无功备用，以适应系统负荷的变化并满足运行的可靠性。无功备用容量即无功设备裕度.它包括以下三个部分:①发生故障时的裕度;②估算误差的裕度;惨节假日及气候突变日的裕度。通常无功备用容量取无功负荷的7%~8%，有时也要进行分析计算后才能确定。 运行方式选择进行无功功率平衡计算时.一般取对应最大无功负荷及最小无功负荷运行方式进行平衡。根据最大负荷求出电容性无功补偿设备容量.根据最小负荷求出电感性无功补偿设备容量。
