5.6.- 高压和电气保护系统

如今,电气系统可以说是世界上最大的互联系统之一。从小城镇到整个国家,数百公里的电力线相互连接。即使在海底,岛屿之间也有地下电缆,以满足这些人口的能源需求。

高压电气系统是极其复杂的,因为它必须将某些电气变量控制在一定的范围内,不能变化。电压、频率和谐波水平是一些持续监测的电气参数。另外,电流和有功和无功功率流量以及功率因数也是其他决定性参数,以保证输送的电能有足够的质量和效率。此外,为了避免对电网造成不可逆的破坏,高压系统中还设有保护继电器,其目的是为了保护这些网络免受电气故障、雷击、错误操作等影响。

由于这些原因,电力系统的设计和管理是一项非常复杂的工作,由于其行为的动态性和不断发生的能量波动。实现电力系统的稳定是至关重要的,为此,分析了构成电力系统的主要元素,包括输电线路、发电机和电能变压器。以分析输电线路的参数为出发点,得到分析和图形表示,从而可以研究其输电能力及其在面对发电和需求的能量波动时的行为。另一方面,考虑到发电电机和电能变压器的运行类型和容量,能够从整体上分析和有利于电力系统的稳定性。

最后,对电力系统对社会环境的主要影响进行了说明,并特别强调了电力能源传输线路。环境影响研究的方法是根据法规和可能存在的减少、消除或补偿影响的措施来制定的。
