角量测 meaning in English

angular measurement

Goniometer - an instrument used in measuring angles
角度计-用来设的度角量测备。
Models with different measurements precision based on phasor measurements are built . as for measurements with low precision , the voltage phasor of nodes with pmus are iterated as state variables . as for the measurements with enough precision , the measurements of pmu are regarded as state results directly
在此基础上，建立了基于相角量测的状态估计模型，对不同精度的pmu量测值采用不同的状态估计模型， pmu精度较低时，在增加量测量冗余度的同时， pmu所在节点的电压相量仍然作为状态变量参加迭代； pmu精度足够高时，直接将pmu的量测值作为状态估计的状态解， pmu所在节点的电压相量不参加状态估计。
