【摘要】：浙福特高压交流输电工程的建成和投运,有利于提高华东电网接受区外经特高压直流传输的电力的能力,增强电网安全稳定水平,满足福建电网盈余电力的送出需要。文章主要研究工程调试阶段,各试验项目主要包括投切空载变压器、主变低压侧投切低容或低抗、1 000 kV侧空充特高压线路、单段特高压线路的解合环、全线合环送电试验、人工单相瞬时短路接地等试验对电网运行方式的调整要求及对电网潮流和系统稳定特性的影响,并提出了安全稳定控制措施,为系统调试中的调度方案编写和执行提供了技术依据。从电网运行方式的角度提出了试验建议,确保了各项调试试验的顺利进行。
[Abstract]:The completion and commissioning of the Zhejiang Ford HV AC transmission project is conducive to improving the ability of the East China Power Grid to transmit power through UHV DC outside the receiving area, and to enhance the security and stability level of the power grid. In order to meet the need of power supply and output of surplus power in Fujian power grid, this paper mainly studies the commissioning stage of engineering. The test items mainly include switching off no-load transformer, switching low capacity or low resistance to 1 000 kV side filling UHV line at low voltage side of main transformer. The test of single segment UHV transmission test, the test of the whole line closed loop and the artificial single-phase instantaneous short-circuit grounding, etc., the adjustment requirements of the operation mode of the power network and the influence on the power flow and the stability characteristics of the power system, are put forward, and the safety and stability control measures are put forward. It provides the technical basis for the preparation and execution of the dispatching scheme in the system debugging, and puts forward some experimental suggestions from the point of view of the operation mode of the power network, which ensures the smooth progress of the commissioning tests.
