voltage phasor 中文意思是什麼
-
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
在此基礎上，建立了基於相角量測的狀態估計模型，對不同精度的pmu量測值採用不同的狀態估計模型， pmu精度較低時，在增加量測量冗餘度的同時， pmu所在節點的電壓相量仍然作為狀態變量參加迭代； pmu精度足夠高時，直接將pmu的量測值作為狀態估計的狀態解， pmu所在節點的電壓相量不參加狀態估計。 -

Phaser including phasor of generators and phasor of bus voltage are most important state variables that reflect stability of power systerm. if it can be measured at real time, dispatcher adopts in effect controlling step based on phasor such that all generators can still be synchronously operated to do this, it is necessary to messure the phasor of generators and to send. them to the power system control center
相角（包括發電機的功角和母線電壓相角）是反映系統穩定性的最主要的狀態量，如果它能夠被實時測量，可以根據相角信息採取有效的控制措施，從而使得發電機群仍然能夠保持同步。為此，必須測量各發電機的功角，並把此信息送到調度中心。 -
