The　series　capacitance　compensation　is　applied　to　realize　the　load　voltage　adjustment　and　stabilization　for　those　distribution　power　systems　which　have　large　voltage　fluctuation　or　could　not　meet　the　requirement　of　load　voltage　level.　The　adjustable　capacitor　is　inserted　into　the　distribution　line　and　its　voltage　is　used　to　compensate　the　line　inductor　voltage　when　load　fluctuates,　which　could　adjust　and　stabilize　the　voltage.　The　load　power　is　sampled　and　the　thyristor　trigger　angle　of　compensation　circuit　is　calculated　in　real　time　to　adjust　the　level　of　capacitance　compensation.　A　distribution　system　model　with　series　capacitance　compensation　is　built　with　PSB　module　in　Matlab　and　the　simulative　result　verifies　the　correctness　of　the　theoretical　analysis.
