Maximum phase-leading capacity dynamic evaluation system of synchronous generator

Abstract

The invention discloses a maximum phase-leading capacity dynamic evaluation system of a synchronous generator. The system comprises monitoring equipment, a dynamic evaluation module, a display module, and a voice module. A maximum phase-leading capacity dynamic evaluation system of the synchronous generator comprise the following steps: acquiring a static parameter in advance and collecting a dynamic parameter in real time; comprehensively considering a generator power angle, stator current, terminal voltage, and a factory variable voltage constraint condition, evaluating the maximum phase-leading capacity of a unit under the current test working condition based on the real-time state quantity collection, and pointing out limitation factors restricting the phase-leading capacity of the unit; collecting reactive power generation of the generator in real time, and synchronously computing the phase-leading depth margin of the unit under the current test working condition. By use of the system and disclosed by the invention, the deficiency of an analysis function of the traditional test monitoring equipment can be remedied, a problem that an evaluation result is distorted since the deviation is existent between an offline computing condition and the actual working condition is solved, the monitoring efficiency on each electric quantity by a tester and the accuracy of the phase-leading depth control of the unit are greatly improved, the safe and stable running of the generator and a power grid in the test period is guaranteed.

Description

Technical field [0001] The invention relates to a dynamic evaluation system for the maximum phase advance capability of a synchronous generator, and belongs to the technical field of power system network source coordination. Background technique [0002] The phase advance operation of the synchronous generator is an important means to enhance the voltage regulation capability of the power grid, which is of great significance to the safe and economic operation of the power grid. The maximum phase advance capability of the generator is closely related to the design parameters of the main body and the characteristics of the power grid. Newly commissioned or modified units must be tested to determine their maximum phase advance capability. Therefore, how to accurately evaluate the maximum phase advance capability of a generator set through tests is particularly important. [0003] In order to give the technical personnel a safe confession, it is necessary to prepare a system test plan...
