摘要

针对直流落点增多与接地极选址越来越困难的矛盾问题

设计一种新型接地极设计方案——广域接地极。据此

首先建立了广域接地极的等效数学模型

该模型辅以场路耦合算法可以对分流情况和运行工况进行计算。随后根据广东电网直流工程现状和后续直流建设情况构建了广东电网广域接地极

并进行了可行性分析。结果表明

广域接地极辅以合适的均流措施可以满足多回直流共用的需要

且具备长期解决后续直流工程接地极问题的理论可行性

值得进一步研究。

Abstract

With the increase in HVDC Project and more and more difficult to select location for ground electrodes

a new grounding electrode design-WAN grounding electrode was put forward.Accordingly

the equivalent mathematical model of WAN grounding electrode was established

and the model supported by field and circuit coupling algorithm can calculate and forecast the current distribution and operating conditions.Then

the WAN grounding electrode was established according to the Guangdong Power Grid project status and follow-up HVDC project

and the possibility was analyzed.The results show that if WAN grounding electrode supported by appropriate measure of current distribution

it can satisfied the needs of multi-loop HVDC

has the theory feasibility of long-term solution HVDC project grounding electrode problem

and is worth further studying.to solve the difficulty of in a long time

it worthy of further study.
