The Research Of The Reactive Compensation Of Nanning Power Network

Carrying on the reactive voltage to the power network to compensate, both affects the system voltage quality directly, and relates the power network economy operation important question.Nowadays, the power network reactive compensation of Nanning still have some questions: The capacity is insufficient, most transformer substations don't compensate by 20% of main transformer capacity, and reactive power cannot form lamination distributes and balances. The transformer substations almost do not reserve capacity when it comes to load peak; System dynamic reactive power compensation is insufficient. The rate of condenser bank failure is high, and some turn oneself in post-natal leaves unused.This article in view of reactive power compensation question in Nanning power network, the main research content includes below parts:(1) According to national laws and regulations, in transformer substation the algorithms of reactive power compensation capacity are quite sole At present, the design capriciousness of transformer substation reactive power compensation capacity is so big that the reactive power compensation design is unreasonable. Therefore the theory reactive power compensation need to be studied and analyzed.(2) As to the Nanning power network reactive voltage question which exposes, the balance analysis to the existing reactive power canceller and the capacity of Nanning Power supply bureau should be carried on, and the Nanning power network existing voltage reactive voltage adjustment method analyzes and appraises should also be carried on. At last put forward the reliminary improvement reactive power compensation proposal.(3) According to above findings, with the principle and experience which relate to the technology the voltage and reactive power electric power management, the compensation disposition principle of Nanning power network reactive power and the suggestion of voltage reactive power management measure are proposed.
