Question

Table 2 describes the summary of our case study
which the worst case appeared when there is no arrester
installed, since 35 kA of lightning current level has
already caused the transformer to breakdown. The best
option is to comprise at least one surge arrester in the
system to protect the transformer and for the case when
only SA1 was installed (Case iii), it is the best arrester
placement option in order to ensure the voltage level at
service transformer within the safety margin in the
presence of unpredicted very high transient current level
injection. The voltage has been clamped to safety level
earlier at the substation entrance as to protect the first
equipment that is the capacitive voltage transformer. As
the voltage propagates through the system, it is observed
that the voltage is still within the safety margin although
maximum current is injected to the system.

The modeling concept and parameter selection to
model a substation were presented for the simulations of
substation performance in order to investigate the failure
probability of crucial component in the substation. The
validation of the result was earlier compared with
previous work done by Savic and Stojkovic to make sure
the model was valid. The results showed that the default
arrangement of TNB substation (Case i) was over
protected which the cost of implementation of such
arrangement is high. The placement of arrester is
crucially needed in order to optimize the substation
performance in term of its reliability and cost effective. It
was suggested that the arrester was best suited for
optimized performance if it was installed at the substation
entrance compared to towards the end of substationconnection that was near the service transformer, since
the first arrester could deal with and maintain the voltage
level within safety range even though with a high current
injected. Since the risk of vandalism and mugging
activities of TNB equipment was reported to be really
critical in recent days, therefore, such optimized
substation design is considerably needed in order to have
a more cost effective station as well as reducing the risk
of reckless behavior by irresponsible public and at the
same time maintaining the reliability of the station in the
presence of stresses to the system.

Answer 1

Table 2 describes the summary of our case study which the worst case appeared when there is no arrester installed, since 35 kA of lightning current level has already caused the transformer to breakdown. The best option is to comprise at least one surge arrester in the system to protect the transformer and for the case when only SA1 was installed (Case iii), it is the best arrester placement option in order to ensure the voltage level at service transformer within the safety margin in the presence of unpredicted very high transient current level injection.
表2 描述的是我们个案研究的概要，这是一种由于35千瓦雷电电流电平已造成变压器击穿在没有安装避雷器时出现的最恶劣的案例。最佳选择是在设置中最少安装一台过电压吸收器来保护变压器，而且在这种情况下只有安装电压吸收器1（案例iii）时才是最佳的避雷器安置选择，借以确保运转变压器的电压电平在安全限度内在面临不可预测的瞬间极高电流电平的注入。
The voltage has been clamped to safety level earlier at the substation entrance as to protect the first equipment that is the capacitive voltage transformer. As the voltage propagates through the system, it is observed that the voltage is still within the safety margin although maximum current is injected to the system.
至于保护第一台设备，即电容式电压互感器，电压早在变电站进流段已经固定到安全电平。尽管最大的电流被注入系统，但是随着电压通过系统传导电压仍然十分明显地维持在安全限度之内。
The modeling concept and parameter selection to model a substation were presented for the simulations of substation performance in order to investigate the failure probability of crucial component in the substation. The validation of the result was earlier compared with previous work done by Savic and Stojkovic to make sure the model was valid.
为了要调查变电站关键部件的失效概率，模拟电站的建模原理和参数选择曾被引入变电站性能的模拟。为确保模拟是有效的，结果的确认与萨维克(Savic)和斯托基科维克（Stojkovic）做过的早期试验提前进行了比较。
The results showed that the default arrangement of TNB substation (Case i) was over protected which the cost of implementation of such arrangement is high. The placement of arrester is crucially needed in order to optimize the substation performance in term of its reliability and cost effective. It was suggested that the arrester was best suited for optimized performance if it was installed at the substation entrance compared to towards the end of substation connection that was near the service transformer, since the first arrester could deal with and maintain the voltage level within safety range even though with a high current injected.
结果显示，国家电力局的电网变电站不履行责任的安排（案例i）过分受到保护，这一点即这种安排的执行成本甚高。根据其可靠性与成本效率，为了优化变电站的实际效能，安置避雷器尤为需要。与安装在靠近服务性变压器的配电接线的末端相比，如果把避雷器安装在变电站的进流段，建议避雷器应与优化变电站的实际效能成最佳匹配，因为尽管会有高电流注入，第一个避雷器可能会在安全范围内应对并维持电压电平。
Since the risk of vandalism and mugging activities of TNB equipment was reported to be really critical in recent days, therefore, such optimized substation design is considerably needed in order to have a more cost effective station as well as reducing the risk of reckless behavior by irresponsible public and at the same time maintaining the reliability of the station in the presence of stresses to the system.
有报道说，由于近日TNB设备的恶意破坏和抢劫冒险行为存在链锁式反应现象，因此，为了实现更高的成本效益，同时减少那些没有责任心的人们不计后果的冒险行为，以及与此同时在系统处于重压中保持站点的可靠性，这种优化电站设计势在必行

Table 2 describes the summary of our case study which the worst case appeared when there is no arrester installed, since 35 kA of lightning current level has already caused the transformer to breakdown. The best option is to comprise at least one surge arrester in the

表2 阐述我们案例研究的总结，最糟的案例是当没安装避雷器时，雷电的35kA 电流电平已造成变压器的故障损坏。可选择的最佳办法是在系统里最少安装一个电涌放电器来保护变压器，而这个只有安装一个电涌放电器的例子（案例iii）,在面临不可预测的极高瞬变电流值的侵入，为确保变压器的电压值是在安全裕度之内，这是最佳的避雷器安置选择。

The voltage has been clamped to safety level earlier at the substation entrance as to protect the first equipment that is the capacitive voltage transformer. As the voltage propagates through the system, it is observed that the voltage is still within the safety margin although maximum current is injected to the system.
为保护变电站的第一个设备，电容式电压互感器，电压较早时在变电站的进线段已被限制在一个安全值水平。随着电压通过系统，虽然注入了最大电流，电压值仍然维持在安全裕度之内。

The modeling concept and parameter selection to model a substation were presented for the simulations of substation performance in order to investigate the failure probability of crucial component in the substation. The validation of the result was earlier compared with
previous work done by Savic and Stojkovic to make sure the model was valid.
为了要调查变电站关键部件的失效概率，这里提出仿真变电站性能的建模理念及变电站模型的参数选择。为确保模型的有效性，在较早时已将结果与Savic 和Stojkovic过去的研究成果作比较来验证。

The results showed that the default arrangement of TNB substation (Case i) was over protected which the cost of implementation of such arrangement is high. The placement of arrester is crucially needed in order to optimize the substation performance in term of its reliability and cost effective. It was suggested that the arrester was best suited for optimized performance if it was installed at the substation entrance compared to towards the end of substation connection that was near the service transformer, since the first arrester could deal with and maintain the voltage level within safety range even though with a high current injected.
仿真结果显示，国家电力局的电网变电站（案例i）的缺省安排有过分保护之嫌，这种安排的成本很高。为优化变电站的可靠性与成本效率的体现，避雷器的安置至关重要。鉴于尽管被注入高电流，第一个避雷器可以处理其电压值及将之维持在安全范围内，建议将避雷器安装于变电站的入口处，这比起安置在接线后部靠近厂用变压器的位置，更合适于优化其性能。

Since the risk of vandalism and mugging activities of TNB equipment was reported to be really critical in recent days, therefore, such optimized substation design is considerably needed in order to have a more cost effective station as well as reducing the risk of reckless behavior by irresponsible public and at the same time maintaining the reliability of the station in the presence of stresses to the system.
根据报导，近日国家电力局的设备被恣意毁坏及抢劫的风险确实严重；既然如此，为了一个拥有成本效率的变电站，并能降低不负责的公众鲁莽行为的风险，同时，在系统面临压力之下维持变电站的可靠性，这种优化变电站的设计是相当需要的。
