摘要： 分析电力行业变电站的阀控式铅酸蓄电池在线放电未得到推广的原因；从而引出逆变并网远程放电这种远程放电方式的必要性，一是节约放电核容成本，释放运维人力；二是放电过程全程无热量，安全可靠，三是适应电力系统自动化的要求，有效规避人工放电核容的操作风险；四是响应国家“节能减排”方针；五是微电网发展要求；然后再阐述逆变放电的安全性保证措施，逆变并网远程放电技术成熟是保证蓄电池远程放电系统安全性的首要条件；并阐述单向二极管技术以及线路自动切换可有效保障蓄电池永远在线，从而保障变电站的安全性；变电站远程放电逆变并网功率小，不影响公网；各种国家强制认证的并网标准，要求逆变设备投入使用前必须经第三方认证机构验证满足规范规定才可投入使用，这些保障措施保证了逆变并网放电的安全性，以利于逆变并网方式远程放电系统在变电站中推广应用。

Abstract:

 This paper first analyzes the electric power industry of substation VRLA battery discharge online have not been promoted the reason which leads to the necessity of grid connected inverter; remote discharge this remote discharge mode, a discharge of the nuclear capacity is to save cost, release maintenance manpower; two is the discharge process of full free heat, safe and reliable, the three is to adapt to the automation of electric power system the requirements, effectively avoid the risk of nuclear operation capacity of artificial discharge; four is the national energy conservation policy; five is the micro grid development requirements; and then introduces the safety guarantee measures of inverter discharge, inverter grid connected remote discharge technology maturity is the prerequisite of ensuring the safety of the battery remote discharge system and describes the one-way diode; automatic switching technology and circuit can effectively protect the battery always online, so as to guarantee the safety of substation substation far; The discharge process of inverter power is small, does not affect the public grid; various national compulsory certification standards, requirements of inverter equipment should be verified by third party certification body meets the specification can be put into use before using these security measures to guarantee the safety of the inverter discharge, for inverter remote discharge system applied in Substation.

Key words: inverter grid connected, remote discharge, safety, human cost, avoid operational risk, energy saving and emission reduction
