Abstract

The proven advantages of digital technology for power system protective relays are now commonplace in the power producing and delivery industry. Digital relays provide unsurpassed reliability and extended capabilities at an economical cost. Keeping pace with the testing and commissioning requirements of these devices has proven to be a challenge for both protective relay engineers and technicians. Although testing procedures have been well defined for single-function electromechanical (EM) protection devices, modern relay test procedures have been left to the utility to develop, creating possible shortcuts that may compromise the protection system operation.
数字继电器测试和调试的重要考虑因素
数字技术在电力系统保护继电器中的优势已被证明在电力生产和输送行业中是司空见惯的。数字继电器以经济的成本提供了无与伦比的可靠性和扩展能力。跟上这些设备的测试和调试要求已被证明是保护继电器工程师和技术人员的挑战。虽然测试程序已经很好地定义了单功能机电(EM)保护装置,但现代继电器测试程序已经留给公用事业公司来开发,这可能会创造可能危及保护系统运行的捷径。
