描述
ABB TPS02是一款汽机保护子模件，主要用于监控和保护汽轮机的安全运行。以下是其产品详情：
技术架构
冗余输入：采用三冗余输入设计，通过三块独立模件同时采集转速、功率、压力信号，避免单点故障。
逻辑判断：终端单元对三组信号进行“三取二”表决，仅当至少两组信号触发保护时才执行跳闸，确保保护动作的准确性。
功能解析
超速保护（OSP）：当转速超过额定值103%或功率超限且油开关开启时，触发超速保护，关闭高压/中压调阀，防止飞车事故。
高压遮断（EHC）与低压遮断（TRIP）：EHC泄压所有阀门油动机，TRIP直接切断汽机控制油路，两者启动转速均设定为额定值110%，实现双重保险。
功率不平衡保护（PLI）：对比电负荷输出与中压缸排汽压力，当机械功量输入超限值时短暂关闭中压调阀，可将功率波动抑制在±2%以内。
硬件设计
全焊接密封：采用Taylor焊接技术，消除螺纹接头或垫圈的失效风险，适应高温高压环境。
热插拔模块：电子线路板支持现场更换，自动配置功能减少停机时间。
穿透玻璃（TTG）技术：在防爆场合无需开盖即可操作，节省维护时间。
通讯能力
协议支持：兼容PROFINET、PROFIBUS等主流工业总线，适配ABB Symphony、Infi90等控制系统。
扩展总线：通过扩展总线与多功能处理器（MFP）实时传输转速、功率等关键参数。
独立运行：即使控制系统数据总线故障，TPS02仍能通过本地逻辑执行保护功能。
ABB’s TPS02 is a steam turbine protection module primarily used to monitor and protect the safe operation of steam turbines.The following are product details:
Technical Architecture
Redundant Input:A triple-redundant input design uses three independent modules to simultaneously collect speed,power,and pressure signals,preventing single points of failure.
Logical Decision:The terminal unit performs a”two out of three”vote on the three signals,tripping only when at least two signals trigger the protection,ensuring accurate protection action.
Functional Analysis
Overspeed Protection(OSP):When the speed exceeds 103%of the rated value or the power exceeds the limit and the oil switch is open,the overspeed protection is triggered,closing the high-pressure and medium-pressure regulating valves to prevent runaway accidents.
High-Pressure Trip(EHC)and Low-Pressure Trip(TRIP):EHC relieves pressure from all valve oil actuators,while TRIP directly disconnects the turbine control oil circuit.Both start-up speeds are set at 110%of the rated value,providing dual protection.Power Imbalance Protection(PLI):Compares the electrical load output with the intermediate pressure cylinder exhaust pressure and temporarily closes the intermediate pressure regulating valve when the mechanical power input exceeds the limit,limiting power fluctuations to within±2%.
Hardware Design
Fully Welded Sealing:Utilizes Taylor welding technology to eliminate the risk of threaded joints or gasket failure,enabling compatibility with high-temperature and high-pressure environments.
Hot-Swappable Module:Electronic circuit boards can be replaced in the field,and the automatic configuration function reduces downtime.
Through-Glass(TTG)Technology:Operates without opening the cover in explosion-proof environments,reducing maintenance time.
Communication Capabilities
Protocol Support:Compatible with mainstream industrial buses such as PROFINET and PROFIBUS,and compatible with control systems such as ABB Symphony and Infi90.
Expansion Bus:Real-time transmission of key parameters such as speed and power to the Multi-Function Processor(MFP)via the expansion bus.
Standalone Operation:Even if the control system data bus fails,the TPS02 can still execute protection functions through local logic.
