By starting from the configuration space generating functional for gauge theory obtained by using the Faddeev Popov methed, the Ward identity under general non Abelian transformation in configuration space is deduced.

Canonical Symmetry in a System with Singular Lagrangian and Ward Identities;

Four subgroups of conformal group and conformal ward identities were derived.

The generator of gauge transformation for Spinor QED has been constructed,the phase-space generating of Green function is obtained by the rule of path integral quantization of Faddeev-Senjanovic method,and canonical Ward identity is also derived in this system,finally quantal consernation laws are gived.

On the basis of Ward equivalent the impact of reactive power in adjacent voltage control areas is considered, the existing areal voltage control strategy is improved and taking the New England power system for example the improved areal voltage control strategy is simulated.

This paper, by accounting for static ward equivalent method, probe.

This paper starts from the actual conditions in the power system,analyzes the characteristic of the Ward equivalent method and the offline distributed power flow calculation,and abstracts the data requirement model of the offline distributed electronic network power flow calculation.
