控制系统-快速甩负荷英中对照翻译文件 |
1. The control system shall accommodate runbacks to various target output. Two (2) independent redundant automatic runback systems shall be supplied. Runback rates shall be field adjustable over the entire range. With the Bid, the Bidder shall provide the various runback target output and runback rates. 控制系统应适应各种工况输出功率情况下的快速甩负荷(runback)的发生。应提供两(2)个独立的冗余自动快速甩负荷系统。应可在完整范围内对快速甩负荷的速率进行现场调节。在投标书中,投标方应提供各种快速甩负荷的目标输出和快速甩负荷的速率。
2. The Bidder shall provide in his Bid a description and block diagram of the entire control system. 投标方应在其投标书中提供关于整个控制系统的说明和结构图。
3. Supplier shall provide a load limiter which shall be capable of sending load limit position signals to NI for indication and shall be capable of receiving the upper and lower limit setting signals from NI to limit the load control. 供方应提供负荷限制器,该限制器应能向核岛发送负荷极限位置信号作为指示,并能从核岛接收上限和下限设定信号来对负荷控制进行限制。
4. The automatic tracking control system shall maintain the load limit setting at a value higher than the normal demanded turbine load. With the Bid, the Bidder shall provide this value according to its practice. 自动跟踪控制系统应保持负荷极限设定的数值高于正常所需的汽轮机负荷。其投标书中,投标方应根据以往经验提供数值。
5. If there is a maximum pressure limitation on the high-pressure section of the turbine, a means shall be provided to avoid exceeding that limit. 如果汽轮机的高压部分有最大压力压力限制,则应提供措施来避免超过该极限。 |
