Description

风能热电联供装置
技术领域
本发明涉及风力发电技术，特别是一种由风力发电机、储热器、相变储热介质、电加热器、蒸汽管、换热水管、换热水阀、蒸汽罐、汽轮发电机、蒸汽发电调节阀、蒸汽供热管、供热调节阀等组成的风能热电联供装置。
背景技术
在现有技术中，并网风力发电技术已得到广泛地应用，它的工作原理是风能通过风力发电机发出交流电，经过整流变成直流电，再经变流器变成与电网相同频率、电压、相位的电能进行并网输送得到电能；它存在的不是之处是：当电网用电处于低谷时段时，就无法接受风力发电机发出的电能，所以此时风电场就要弃风停止发电，造成很大的能源损失。
发明内容
本发明的任务是提供一种风能热电联供装置、能有效的克服现有技术的不足之处，全天24小时不弃风，始终发电储能，待电网需要供电时，随时供给。
本发明的任务是这样完成的：将风力发电机发出的交流电，通过电加热器熔化储热器中的相变储热介质，储存高温热能；当需要向电网送电时，打开换热水阀，通过换热水管、蒸汽管将储热器中的热能转变成蒸汽，送入蒸汽罐中。打开并调节蒸汽发电调节阀门，就可以控制汽轮发电机组，发出与电网相同频率、电压、相位的电能与电网并网输送；打开蒸汽供热调节阀，通过蒸汽供热管、还可提供生产、取暖供热。
本发明的有益效果是：能够全天候利用风能发电储存热能，通过汽轮发电机、发出高质量的电能并网输送；省掉昂贵而复杂，且易出故障的庞大电子系统。
附图说明
附图为本发明的原理结构示意图
具体实施方式
下面结合附图及实施例对本发明作出进一步详细说明
在附图中，将风力发电机1发出的交流电，通过电加热器4熔化储热器2中的相变储热介质3，储存高温热能；当需要向电网送电时，打开换热水阀7，通过换热水管6，蒸汽管5将储热器2中的热能转变成蒸汽，送入蒸汽罐8中。打开并调节蒸汽发电调节阀10，就可以控制汽轮发电机组9，发出与电网相同频率、电压、相位的电能与电网并网输送；打开蒸汽供热调节阀12，通过蒸汽供热管11还可以提供生产、取暖供热。
